UK's Brown to unveil election plans after failed plot

Despite trailing the opposition Conservatives by 10 points in the latest opinion poll, Brown will tell members of his center-left party that an historic fourth consecutive election victory is still within their grasp.

"We can beat them, we must beat them and we will beat them," Brown will say in a speech to the party in which he plans to lay out his election strategy. His office released extracts of the speech in advance.

With Britain saddled with a record budget deficit after the worst recession in more than 50 years, the main parties have effectively already begun the election campaign with clashes over the economy and public spending.

Brown, who has struggled to quell dissent within his party since replacing Tony Blair in 2007, will seek to portray the Conservatives as "a party of austerity." Their leader David Cameron has said he will cut public spending faster and further than Labour if he wins the election due by June.

"We will contrast Labour -- the party of aspiration -- with the Tories, the party whose only pledge to the mainstream majority is one of austerity," Brown will say.
