UKIP's main policy to try and get the UK out of Europe and up on until recently they have not had much input in the UK's General Election.
However now opinion polls have been suggesting that they would poll at
least 10% in an General Election.
This more worrying for the Tories as it is mainly Tory voters who have defected to UKIP. So for the Tories to win a majority in the next general election they need to get the 10% back from UKIP.
Labour do not need to worry so much about the UKIP vote. However the Labour Party would hope that UKIP do not get a lot votes. As UKIP would make it very difficult for Labour to govern effectively.
Recently UKIP leader Nigel Farage has disowned the party 2010 manifesto. Saying that UKIP will write a new manifesto after the European elections.
Now UKIP realise they can return some of their candidates to the House of Commons.
They are now trying to be a little more tactful and are trying to hold on to their 10% of the voting public and they hope that this will be sustained until the next General Election.
