Voters in constituencies that could determine the outcome of Britain's election want a change of prime minister but many are unconvinced opposition leader David Cameron has what it takes, according to a poll commissioned by Reuters.
The latest Reuters/Ipsos MORI poll of battleground or marginal seats - constituencies narrowly held by the ruling Labour party - shows that voters rate Labour leader Gordon Brown more highly than Cameron on almost all leadership measures.
However, the poll also shows nearly 60 per cent of voters want a leader who represents change.
It is a dilemma that helps explain why the country is still on course for a so-called hung parliament in which the Conservatives are the largest party but fall short of an overall majority in the 650-seat House of Commons.
"Many voters in these key marginals do think that the Conservatives are ready to govern and that Cameron is ready to be Prime Minister, but a significant minority still have their doubts," said Ipsos MORI's Helen Coombs.
Ipsos MORI polled 1,008 adults between March 30 and April 5 in key marginals: seats the Conservatives must win if they are to secure an outright win in the May 6 election.
It found 37 per cent of those polled believed Gordon Brown best understood the problems facing Britain compared to 30 per cent who said Cameron. Forty-one per cent thought Brown would be best in a crisis compared to 30 per cent who said Cameron.
Brown was seen as having a better understanding of world problems and a better grasp of detail than his Conservative opponent, and was ahead on questions of who was the most capable leader. In national polls, Cameron is seen as the most capable.
Despite Brown's relatively strong showing in the marginals, the poll showed that after 13 years of Labour rule, the country wants change: the central message of the Conservative party who have adopted "Vote for Change" as their campaign slogan.
When asked if Britain needed a Prime Minister who brought fresh thinking and a new approach to secure economic recovery or one who could draw on past experience, 57 per cent opted for the fresh approach while 40 per cent said experience.
A survey of economists conducted by Reuters last month showed they would rather have Conservative shadow business spokesman Ken Clarke as Chancellor than shadow Chancellor George Osborne.
An Ipsos MORI national poll in February found that, for the first time since 1987, leaders were as important as policies in helping people decide who to vote for.
This means Britain's first ever televised leaders' debates could make a significant difference, particularly as nearly half of voters have not yet made a final decision on how to vote.
Some 46 per cent of those polled in marginals say they may change their mind about who to vote for and 60 per cent say the debates will be important in helping them decide how to vote. The three debates will be held on April 15, 22 and 29.
Overall voting intentions are little changed from the last Reuters/Ipsos MORI poll two weeks ago.
Some 38 per cent of voters said they would vote Conservative at the next election - up from 37 percent last time - and compared to 41 percent who said they would vote Labour.
That represents a 5.5 per cent swing to the Conservatives from Labour compared to the last general election in 2005. The Conservatives need a swing of 6.9 per cent nationally to gain a majority in the House of Commons.
