Mr Tony Blair is preparing to set out his vision of the "opportunity society" that will be his mission for a third term in office.
The British Prime Minister promises welfare reforms intended to give people chances rather than respond to their problems.
Mr Blair will pit this against what aides dubbed the "minimalist" politics of Tory leader Michael Howard.
He is also expected to tell doubters in his own party the Government's greatest advances have been made by the boldest new Labour reforms.
He will claim that improvements will not come from simply spending more on existing state structures and will argue that "New Labour" values must run through Labour's election manifesto and, if elected, reach into every area of the Government's work.
Mr Blair will reject the Conservative notion that Britain is in decline, citing a record period of economic growth and employment paying for public sector investment.
His speech, to the Institute for Public Policy Research, comes after Mr Howard suffered another poll battering.
The Tory leader's speech to his party's annual conference last week tried to capitalise on waning public faith in the prime minister. However, Mr Blair was voted most trusted party leader in an poll that place Mr Howard third behind Liberal Democrat Charles Kennedy.
