British Prime Minister Tony Blair will set out a platform of "bold and radical" New Labour reforms designed to strengthen Britain's economy and public services.
In his keynote speech to Labour's annual conference in Brighton, Mr Blair will set out a policy agenda focusing on the economy, education, health, transport and law and order.
Mr Blair's plans are sure to be seen as an attempt to secure his personal political legacy by projecting his vision of Britain into the years - beyond his exit from Downing Street.
He will argue that just as the party had to modernise to clinch its 1997 general election victory, it now has to modernise again in order to be ready to deal with a range of complex challenges resulting from the impact of globalisation, and the need for further public service modernisation.
The Labour leader will warn that unless the governing party matches its values with an honest understanding of the realities facing Britain - unless it makes the changes necessary to "own" the future - then "we will fail".
Aides said that the speech would be "policy rich", adding that it will contain a passage on Iraq. But they indicated Mr Blair will not refer to the issue of the party leadership.
