Could we still be in line for an April election? Speculation rolls on.

An ICM poll for the Sunday Telegraph today showed the Conservatives on 39 per cent (down 1 point), Labour on 30 per cent, and the Liberal Democrats up 2 to 20 per cent. This is the first ICM poll to show the Tories on less than 40 per cent since last June. Continuing the recurrent theme of recent polls, if these results were repeated at the general election, they would result in a hung parliament.

It's heartening for Labour. In an interview with the Observer, Gordon Brown appeared buoyed by his recent success in Northern Ireland, the UK's emergence from recession (just about) and signs of Tory inconsistency on policy. "I'm not complacent," he said, using a word generally reserved for the obvious front-runner. "But Labour can still win it. I'm absolutely sure of that."

So, it's possible that Labour could attempt to capitalise on this feeling that the political tide is turning, and wrong-foot the Tories by calling the general election a couple of weeks earlier than the expected date, 6 May. Both the Telegraph and the Mirror report that this is what Labour strategists are advising Brown to do.

There is a strong case for Labour to call the election in mid-April. It would bypass the potentially problematic growth figures, released at the end of April, which could show Britain falling back into recession. The Tories are wobbling on economic policy, and, at the moment, Brown can still claim to have led the country out of recession.

But lest we forget, the improvement in the polls for Labour that everyone is so keen to shout about gives them, at best, a hung parliament, and nothing approaching an outright majority. If Brown genuinely believes that Labour can still win it -- and his self-belief is notoriously unshakeable -- it seems more likely that he will want to hang on in there and narrow the lead further, rather than take rash action.
