David Cameron: 'Recovery out of recession will be difficult'

Prime Minister David Cameron has warned that the recovery from the recession will be ''difficult'' as shares continue to fall and investors worry about the global economic outlook.

Addressing the Canadian parliament in Ottawa, Mr Cameron said the economy was still suffering from the economic collapse of 2008.

Finance ministers and central bankers from the G20 group of countries have promised a "strong and co-ordinated response" to the problem.
