The Conservative Party in Britain will fight the coming general election under the slogan "Vote for change".
Leader David Cameron was expected to tell delegates at a conference in Brighton this weekend that the party can offer people real change.
However, recent polls have suggested that the Conservatives' lead over Labour may be narrowing.
An Ipsos/Mori poll for the Daily Telegraph, published on Friday, suggests the lead is five points - down from 28 in September 2008. It gives the Conservatives 37%, Labour 32% and the Liberal Democrats 19%.
The election, which must be held by June. is expected to take place on 6 May. Prime Minister Gordon Brown this week revealed Labour's election slogan would be "A future fair for all".
