As opinion pollsters seek to discover more about what is behind the Lib Dem surge, the ICM poll for today's Guardian seems to confirm that Clegg is being seen as the 'anti-politics' candidate who can be trusted more than the other two big party leaders.

UK business leaders became much more confident in Liberal Democrat leader Nick Clegg's during April, according to a poll by ComRes published today (Monday).

Between March and April, business confidence in the better known UK politicians picked up, but Clegg was the main beneficiary. Asked if they had confidence in Clegg, 41 per cent of the 170 chief executive officers and directors of the UK businesses said yes.

That rating is up from 20 per cent in March. Confidence in David Cameron rose to 65 per cent from 55 per cent of respondents, and in Gordon Brown to 28 per cent from 19 per cent.

Comment

Party leaders marked ‘World Poverty Day’ yesterday, but the issues are likley to disappear until the TV debate on Thursday, which will focus on foreign policy.

Dealing with ongoing air chaos is likely to dominate the news agenda.

Support for proportional representation seems to be strong according to the latest poll from YouGov tonight which finds only 16 per cent of the population now opposing it and 29 per cent still undecided.

Comment

Party leaders will mark ‘World Poverty Day’ today by outlining their visions of how the UK should act on its responsibility to the wider world.

It comes after a ranking carried out by the World Development Movement suggested that none of the three main parties score well on their plans to tackle key international development issues.

The Conservatives fare particularly poorly (three out of ten), Labour (five out of ten), and the Liberal Democrats (six out of ten) receive a middling rating. The Greens (eight out of ten) come out on top on issues such as trade justice, international aid and IMF reform.

Two early polls for the Sunday papers show the Lib Dem surge holding up following the Sun/YouGov poll last night with significantly growing support for a hung parliament.

Two other things of note:

(i) The surge may have been underway before the TV debates on Thursday (ICM)

(ii) Much of the new support seems to be coming from under 45s, who were previously unlikely to vote (ComRes).

A YouGov poll for the Sun following the prime ministerial debates, gives a huge boost to the Lib Dems. It puts the Conservatives in first place, the Lib Dems in second and Labour third in terms of share of the vote:
