Conservative Party activists are due to gather for their last nationwide meeting before the start of the general election campaign.
The party is holding its two-day spring conference in Brighton at a time when recent polls have suggested that its lead over Labour may be narrowing.
On the eve of the conference, it was revealed that the Tories' election slogan will be "vote for change".
This message is likely to be central to David Cameron's main speech on Sunday.
Labour will use the Tory conference as an opportunity to launch a new poster attacking the shadow chancellor George Osborne.
The Liberal Democrats say only they offer a change to the existing way of conducting politics.
The election must be held by June but is expected to take place on 6 May.
'Unsurprising slogan'
Mr Cameron is likely to use his speech to inspire activists ahead of the upcoming campaign but also to set out the extent of the economic challenges facing the next government.
Revised figures published on Friday confirmed that the UK did emerge from recession slightly stronger than initially thought in the last three months of 2009 but all parties agree the recovery is still fragile.

Among those giving speeches on Saturday will be Mr Osborne, the party's official election co-ordinator, and shadow foreign secretary William Hague.
The Conservatives are also expected to unveil Professor David Kerr, a leading cancer specialist, as the party's new health adviser.
Prof Kerr was once a prominent supporter of Tony Blair and Labour's health reforms but said on Friday that he believed the Tories were now best placed to take the NHS forward.
BBC political correspondent Gary O'Donoghue said the Tories had been using the word change for months, so their choice of slogan was neither "original nor surprising".
"This weekend's spring conference will see little in the way of new policy announcements," he said.
"[It] will attempt to persuade the voters that a modernised Conservative party is not just able to deliver change, but has also succeeded in really changing itself."
Choice - between Mr Cameron and another five years of Gordon Brown - will also be an important word for the Tories, he added.
The Tory conference begins a week after the prime minister revealed Labour's election slogan of "a future fair for all".
This weekend, the party is releasing more pre-election campaign material. An image of shadow chancellor George Osborne is accompanied by the slogan "Chancer not Chancellor".
Danny Alexander, the Liberal Democrat leader's chief of staff, said the election was not a choice between Mr Brown and Mr Cameron.
"It's between the old way of doing politics and the real change represented by the Liberal Democrats.
"For people who want real change, real fairness in Britain there is only one choice: the Liberal Democrats. Labour has totally failed to make Britain fairer, and the Tories can't be trusted to do."
