The Scottish Socialist Party supports independence and is fighting for a Scottish republic.
Colin Fox is leading the SSP into the general election
It wants the people of Scotland to take control of the country's wealth and resources.
Charismatic former leader Tommy Sheridan resigned in November after the SSP said he wanted to retreat "from the frontline of political struggle".
The SSP was created in 1998 out of the Scottish Socialist Alliance and brought together a number of disparate parties.
The party, with Colin Fox as its new leader, sees devolution as offering a "modest democratic change" but says it is still a long way off creating a country with total control of its economy, welfare system and defence system.
It advocates proportional representation, the abolition of the monarchy, full powers for the Scottish Parliament, an end to the Union and the creation of an independent Scottish republic.
Focusing on the election, Mr Fox said: "We will haunt new Labour on their record on the war in Iraq - and we will haunt the SNP.
"We are passionate about independence and both parties seem to have lost their passion."
The party calls for a free, universally accessible education system and wants grants and bursaries to be reinstated across the country.
It is opposed to Britain's Trident nuclear weapons system and has called for UK troops to be pulled out of Iraq.
Among its other policies, the SSP calls for equal pay and pension schemes for women and the abolition of PFI schemes.
In the 2003 Scottish Parliament election, the SSP increased its representation in the Scottish Parliament from one to six.
