Labour slumps to historic defeat
The Prime Minister Gordon Brown is facing a new crisis in the fight to save his job.
On Sunday night, Labour got just 15% of the vote in the UK elections for the European Parliament.
The party was knocked into third place behind the Conservatives and UKIP, Labour's worst result in an election for more than 100 years.
Gordon Brown admitted Labour were going through some tough times: "This is a test not just of our character, and a test not just of the government. This is a test of our beliefs."
Cabinet minister Peter Hain is blaming anger over tax cash going on MPs' expenses, rather than it being a verdict on the PM.
He said: "They're punishing all of us but because we're the governing party, and they expect more of Labour. They've punished us particularly."
Tory leader David Cameron's chuffed with the result though. His party got nearly double what Labour managed.
"We won in almost every part of the country and had some staggering results like topping the poll in Wales," he said.
"Together with the local elections, I think they show an enormous gap opening up between Labour and Conservatives."
Cameron 'delighted' with results
All this means the nightmare for Gordon Brown continues. Right now he's limping on but there'll be a critical meeting with Labour MPs, many of whom want him out, on Monday night.
The PM took a similar beating in local elections last week and a string of senior ministers have quit their jobs in protest at his leadership.
The far-right BNP also had its first successes in the Euro elections on Sunday night.
Protestors in Manchester tried to stop the BNP getting into the town hall to hear the result.
The party has been accused by its opponents of stirring up racial hatred.
Leader Nick Griffin had his car attacked and protestors chased his car down the street. He got in around the back.
The BNP actually came fifth in the voting but it was enough to win two of the 14 MEP seats in the North West of England and Yorkshire & Humber region.
Labour and the Conservatives have called it a "sad moment" for politics.
In a week where ministers were lining up to walk out on Gordon Brown, Peter Mandelson's now seen as his biggest supporter.
But there was further embarrassment for the Prime Minister over the weekend when an email from 18 months ago was leaked to the papers.
UKIP: A hell of an achievement
As well as calling him insecure and angry, Peter Mandelson said the PM spent too much time talking about how he liked X Factor than working out policy.
And now the PM's now been criticised for appointing Sir Alan Sugar.
Gordon Brown was probably hoping hiring him as an advisor on business would be popular but the Tories want it investigated.
They think it breaks rules that BBC presenters must be politically neutral.
