Zimbabwe's ruling party says Robert Mugabe will contest a second round in the presidential election, if necessary.
The Deputy Information Minister said there was no question of President Mugabe stepping down if no clear winner emerged from last Saturday's poll.
Zimbabweans across the country have been sending the BBC their views and concerns of the delayed results.

SUNDAY, 6 APRIL
The mood here is so sombre and depressing, the whole country is beginning to feel like a woman who has just had a miscarriage, after buying clothes and even having a new name for the baby! But we are beginning to get agitated. You might be seeing an Orange Revolution style of millions of people in the streets waving red dismissal cards, wearing red caps, shirts, T-shirts etc, demanding a peoples' government.

I fear for my life since the situation is very tense, ugly and unpredictable. Our lives are in danger here in Zimbabwe. May God be with us and save us from this mess. God please help us out of this situation peacefully.
SATURDAY, 5 APRIL
The situation is calm, but pathetic, people know exactly what they want but can't freely express their views. If a run off is called, people will die.
At the moment there is peace around town and people are doing their business as usual, but their hearts are pregnant with questions, anxiety, uncertainty and confusion. A lot of things have been said concerning the polls that left people confused. The uncertainty has caused even business people to hold on to their consignments, waiting for the outcome of the polls. I think the true spirit of Zimbabweans is being displayed at the moment - looking at the total peace around. Mugabe did great things that even today we will appreciate but I believe we should now test other people's capabilities to lead.
Things are very confusing, looks like we are heading for a civil war and total distruction, its a ticking time bomb, any thing can happen any time.
I have something growing inside of me - a burning rage. I first felt it when, a day to go to the elections, there were armoured vehicles and riot police going round in the streets. We understood the need to keep the peace and for law and order but this was something else - intimidation. I did something that up to now, still makes me shake. I shouted and screamed that no matter what, people were going ahead and would express themselves. Lucky for me, the soldiers did not hear me, otherwise I would now be a guest of the state.
I am a forty year old woman, mother of three children and have never been politically involved in anything until now. The people of Harare are quiet, too quiet. Our land line telephones are being blocked, the phone rings and you do not hear what's being said, or you call a number and there is call failure. This political uncertainty is frightening. People went to the polls to vote. Elections express the will of the people. If the will of the people is no longer respected, then what?
Things are quiet here. There seems to be a similar feeling of being robbed and cheated, of having our tongues cut out of our mouths. The government insults our intelligence - the results are public knowledge yet they refuse to accept defeat. I pray people do not accept that lie and stand up for their rights. They stole the vote in 2002, but I hope they fail this time.
As I write I'm in a hotel in the town of Gwanda in the southern part of Zimbabwe. Life continues as normal out in the streets save the long faces of the town's people. It seems everyone would like a change in the country's leadership. Tsvangirai's leadership style is questionable, but at this point, we're really out of options (we'll take any leader, anyone as long as it is not Mugabe!) People here are really peaceful - if Mugabe dispatches his army and war veterans on the people, he might as well be beating a dying horse for Zimbabweans have no way to retaliate. I feel like we're about to feel the wrath of a true 21st century dictator!

FRIDAY, 4 APRIL
I am in Bulawayo. Everything is calm and peaceful. We patiently await the outcome of the results like everyone else the world over. Despite the uncertainty over the election, life goes on for us. Inflation is still soaring, prices are sky-rocketing and today we have just welcomed a new Z$50m note!!!!
President Mugabe is a gentleman and he will leave office when all this is over. Why is it that the BBC always wants to denounce our hero? Just because he gave land to its rightful owners, refused to be a yes man to whites and told the world about the massacres being carried out by the USA and its allies all over the world. Look at Iraq, Afghanistan and some African Nations. They attack undercover saying they want to bring democracy. Is that democracy? Shame, shame, shame. Mugabe told you that you cannot teach us.
People's calm attitude reflects the nature of the people of Zimbabwe. Many are busy with their own problems like living with hyperinflation and the safety of their families. This restricts them from engaging in politics. Although many, if not all, Zimbabweans would like to see changes that would make life a little more pleasant, they would rather have that without bloodshed. Many wait for a time when power cuts, queues for basic commodities and tough business conditions disappear. Will the victors in the election bring this about?
It is not easy to accept defeat after ruling for such a long period but somehow the regime will come to terms with reality, however painfull it is. The wishes of the people should and will definitely prevail, then, whoever has anything to answer should be made to answer. Justice delayed is justice denied.
We Africans are very greedy. How on earth can an 84 year old man fail to accept defeat in an open election monitored by the whole world? Mugabe should quit now or face the wrath of Zimbabweans. Enough is enough. We are having the most terrible poverty, disease, unemployment and a nosedive economy. The world should support a change here, as failure would mean they are ready to witness refugee camps all over various countries in Africa. The new song now is that we want new blood with vision.
The white community is very worried that they will be the first targets of a Zanu PF clamp down, which has already begun. Yet there is no help from the outside world - not even the British - and we are going to have to die, before anyone comes to our rescue.
It is hard to believe that ZEC is failing to release senatorial results now because of logistical problems. We are not fools to believe that when they were collecting parliamentary results they failed to collect the senatorial results. I suppose they will spring up the same excuse come the presidential result. ZEC please be serious!
THURSDAY, 3 APRIL
The atmosphere here is very stressful, as a Zimbabwean I would like to know who my next Head of State is, but ZEC is holding the whole nation at ransom. I am not able to work or do anything before I know the result of the presidential election. Unfortunately Zimbabweans are now living in a cash economy where they must queue at banks on a daily basis to get money.
My sister who lives in the rural area of Chesvingo, said to me: "I am tired of walking more that 20kms to catch a bus to the city. I am tired of carrying 30kgs of maize for more than 30kms by night to the grinding mill and in some cases loosing some of my maize or maize meal to thieves. My kid now needs proper schooling. I voted for change and if Mugabe wants me to vote again I will vote for change again even under violent conditions".
We are waiting. We dare to hope! I believe that this is the end of the line for him. We are on our way to becoming a true democracy!
And if Tsvangirai can't deliver the goods we'll vote him out too...And I can't tell you how good it feels to call Zanu PF the opposition party.
We feel better running our own show. We Zimbabweans do not want to be pushed. We know you have your watchful eyes but back off. Back off because we can manage without puppets. It's better the military takes over than suffer in your hands.
I am not concerned at all, Zimbabweans are an educated lot, they are a patient lot and most of all they are a peaceful lot. I hate the way the International community have been insinuating havoc which has all come to zero. Give us a chance to run our elections in our own way, our own peaceful way. Zimbabwe is not Kenya, we do not vote on tribal lines.
WEDNESDAY, 2 APRIL
Events of the last couple of days have shown that the people of Zimbabwe are ready for change. Mugabe tried all he could to buy votes from the people but this has obviously not worked.
Mugabe can not be replaced, by a puppet leader in Zimbabwe. Wait for the re-run and you will get the truth - that he is the only one who can rule that country and make Zimbabweans feel at home. If it were not for the sanctions by the West, Morgan Tsvangirai could not even get 1% of votes
We are all waiting like so many times before, waiting for bread, waiting for milk, waiting for fuel - I hope this is the last wait. The most important aspect for us is we cannot WAIT to pick up the pieces and move on. Ten years of our youth has been taken away from us, another ten years to heal and then we will leave this blessed coutry for our children.
The situation in Harare is tense with most businesses having halted production until the election results are announced. My Company for instance has stopped production and we were told in no uncertain terms that it will close down if Zanu PF is retained in power. We are anxious to know the outcome as it determines our future and where my family will be tomorrow.
Mugabe has lost and he knows it. That is why he is so silent. We voted him out and he must put aside his ego, respect us the electorate and step down without plunging the country into chaos. We still have an economic battle to fight so please Mr Mugabe just go and trouble us no more.
The elections were free and fair. There was no violence and people were going about their everyday business after the voting. Right now I am in town enjoying myself, waiting for the final results.
