LONDON, Feb 3 - Prime Minister Tony Blair said on Tuesday he believed Britain's growing public debt was manageable and that now was not the time to cut public spending or raise taxes. "If you look at it in real terms, our deficit is easily manageable and actually better than at most other points in downturns in the past," Blair told a committee of senior parliamentarians. Asked if the government should be thinking about tax rises or public spending cuts, Blair said: "No, because I think the Golden Rule will be met." Chancellor Gordon Brown has formulated a "golden rule" under which the government borrows only to fund investment over the business cycle.||
