Britain's Chancellor of the Exchequer George Osborne speaks at a Thomson Reuters Newsmaker event at Canary Wharf in LondonWith the aid of David Milliken and William Schomberg LONDON (Reuters) – Finance minister George Osborne celebrated a pointy turnaround in Britain's financial system as vindication of his austerity push on Thursday, but said he would no longer chill out his grip on public spending within the years in advance. Obsorne used an incredible soar in forecasts for increase in 2013 and 2014 to taunt the opposition Labour party ahead of a normal election in 17 months' time. As recently as April, Osborne was below heavy criticism from Labour as the economic system flat-lined. The World Monetary Fund also advised him to hurry up spending.
