This may not come as a surprise but the minor party showing is also up 3% to 12%. At a time when the electorate is very volatile and there is huge dissatisfaction with the government there is always a temptation for people to look at the two main parties and say 'a plague on all your houses'.
David Cameron has opened up a sizeable lead over Mr Brown as the best Prime Minister to handle the recession and to lead Britain forward after the next election. In November Mr Brown was ahead of Mr Cameron by 52 to 32 per cent as the right leader to deal with the British economy in recession. They were level pegging last month but Mr Cameron is ahead by 41 to 32 per cent.
Mr Cameron has widened his margin as the right leader to take Britain forward after the next election from 42 to 35 per cent in November, and 43 to 31 per cent in January, to 45 to 28 per cent now.
You will see this in spades at the Euro elections. It happened in 2004, when UKIP overtook the LibDems as the chief beneficiary of the so-called 'dustbin vote' and scored 16% despite virtually no presence in Scotland and Wales. I don't epect UKIP to match their 2004 performance in June, but I do expect the Greens to do much better. Not perhaps as well as their 15% showing in 1989, but I think they may creep into double figures.
