Economy set to dominate an unpredictable race
Standing outside his Downing Street residence in the sunshine, with his cabinet arrayed behind him, Brown ended weeks of shadow boxing by confirming the May 6 date, just a month before the last possible time for an election.
âItâs probably the least well-kept secret of recent years but the queen has kindly agreed to the dissolution of parliament and a general election will take place on May 6,â Brown said, starting his bid to extend Labourâs 13-year grip on power.
The Conservatives lead Labour in opinion polls. But the election result is far from certain as public support for both main parties remains volatile and the opposition faces a big challenge in securing power.
Polls point to a hung parliament in which no party has an overall majority because support for the Conservatives is less efficiently distributed across Britainâs 650 parliamentary constituencies.
An inconclusive election result is rare in Britain and is the nightmare scenario for financial markets, which want a clear outcome and the promise of firm action to tackle a budget deficit running at 12% of GDP.
Conservative leader David Cameron, addressing supporters on the banks of the River Thames opposite parliament, called it the most important election for a generation.
âYou donât have to put up with another five years of Gordon Brown,â said Cameron, 43, a former public relations executive.
How best to run an economy slowly emerging from the worst recession since World War Two is likely to be the central theme in the campaign, entwined with issues such as how best to manage public services in straightened times.
The Conservatives promise to cut the deficit harder and faster than Labour but have also pledged to exempt most workers from a payroll tax rise Labour plans next year.
The 59-year-old Brown, who served as chancellor for a decade before replacing Tony Blair mid-term in 2007, said the recovery was too fragile to be entrusted to the Conservatives.
âBritain is on the road to recovery and nothing we do should put that recovery at risk,â said Brown.
âGet the big decisions right, as we did in the last 18 months since the world recession, and jobs, prosperity and better standards of living will result,â he added.
With the exception of Labourâs landslide victory in 1997, no party has secured more than a 5% swing in the national vote at a general election since 1950. The Conservatives require a swing of 6.9% to secure an outright win.
The new parliament will meet on May 18, the government said. That is later than unusual to give new members of parliament more time to prepare for their career change. It would also allow longer for horse-trading if no party wins a majority.
The outgoing parliament has been tarnished by a scandal over MPsâ expenses. As many as 150 members of parliament are stepping down, many with reputations harmed by the scandal. All the main parties have suffered and some analysts expect fringe parties and independent candidates to win extra votes.
The Liberal Democrats could also play a pivotal role if neither of the larger parties wins a majority.
Adding spice to the campaign will be Britainâs first live television debates â between Brown, Conservative leader Cameron and Liberal Democrat leader Nick Clegg.
Bookmaker Paddy Power said the Conservatives were 1/6 favourites to win, with Labour at 7/2. The odds of a hung Parliament were 13/8.
Spokesman Darren Haines said for bookies âthe most favourable outcome would be a Lib Dem winâ â a 200/1 longshot.
