John Prescott is set to bring the curtain down on Labour's conference as the contest to replace him and Tony Blair at the party's helm gathers pace.
John Prescott has apologised for letting Labour down over the past year.
Mr Prescott, who on Wednesday threw his weight behind Gordon Brown to be the next PM, is expected to quit his post when Mr Blair quits Downing Street.
The deputy prime minister has been at the centre of controversy over an affair with his diary secretary, and hospitality from a US tycoon.
Three people have so far said they will stand for Mr Prescott's job.
As he wrapped up the party's conference in Manchester, he said: "This party has given me everything and I've tried to give it everything I've got.
Home Secretary John Reid will tell delegates he plans to send ministers out to Muslim communities.
"I know in the last year I let myself down, I let you down. So conference, I just want to say sorry."
'Not brow-beaten'
Mr Prescott is not expected to use the speech to say he will stand down as deputy leader when Tony Blair quits as prime minister.
The ministers will encourage communities to "face down extremist bullies", Mr Reid will say.
That is despite the fact that three contenders - Jon Cruddas, Peter Hain and Harriet Harman - have already said they want his job and more looked poised to follow.
The speech follows the controversy which erupted when Mr Reid was heckled during a visit to Leytonstone, east London, as he urged Muslim parents to guard against their children being radicalised.
Demanding discipline
He will tell Labour delegates there must be no "no go" areas.
The deputy prime minister is saying he is proud of what he and Mr Blair had achieved together, despite occasionally agreeing to disagree.
"We will not be brow beaten by bullies, that's what it means to be British," Mr Reid will say.
"Tony, we all know the greatest tribute we can make to your time in office is to find within ourselves the energy, the vision, the commitment, and yes, the discipline to win a historic fourth general election victory," he will say.
He particularly wants to engage with Muslim women who he sees as a moderating influence.
Mr Prescott says the last two leadership elections were a credit to the party and Labour must make sure the next contest is conducted in a "framework of unity".
Crowded field
"I've seen Labour governments, elected with big majorities, driven out within a few years as the party bitterly divided," he will say.
Mr Reid is seen as one of the very few possible heavyweight rivals to Chancellor Gordon Brown for the Labour leadership.
His speech will be closely watched for any clues as to whether he has aspirations for the leadership.
After the emotional response given to Tony Blair's last conference speech as prime minister, Mr Prescott is expected to confirm that Thursday's speech will be his final one as deputy leader.
Mr Prescott has traditionally used his end-of-conference address to deliver a rallying cry to Labour activists - and to poke fun at the Conservatives and Liberal Democrats.
And Mr Blair paid tribute to what he called his vital role over the past 12 years in taking the New Labour message to the Labour Party.
But his speech, due at about noon, comes after a year when he has faced a number of controversies.
Cowboy outfit
He admitted to an affair with his diary secretary, lost his department in the reshuffle and then gave up his official residence of Dorneywood.
And he was hit by controversy over his stay on the ranch of US tycoon Philip Anschutz, the man who wants to get a casino licence for the Millennium Dome and gave Mr Prescott a cowboy outfit.
Mr Prescott has repeatedly denied any conflict of interest and police on Wednesday rejected claims that he had broken anti-corruption laws.
Backbencher Jon Cruddas and ministers Harriet Harman and Peter Hain have already said they want to succeed Mr Prescott.
And Education Secretary Alan Johnson and Commons Leader Jack Straw are among other potential candidates for the deputy leadership.
The speech comes after the Labour leadership suffered a double defeat at the conference in votes on NHS reforms and council housing.
