David Frost, British Chambers of Commerce: "A marked upturn in confidence"
Last week, the ONS sharply revised its GDP data for the UK, saying the economy shrank by 2.4% in the first quarter of 2009, compared with its earlier estimate of a contraction of 1.9%. With these heavy revisions, the BCC said it was far too early to say that recovery is secure.
It added that without continued focus on limiting the impact of the recession, there was still a risk that the economy could "drop off suddenly" and the UK could be heading towards a "W-shaped" recession.
"It is absolutely vital that the improvement in business confidence is nurtured," said BCC director general David Frost.
"Our economy is based on confidence, and wealth-creating businesses need to know they will be given the freedom and flexibility to drive the UK out of recession and into a sustainable recovery."
He added that the proposed increase in National Insurance contributions in 2011 was a "tax on jobs" which should be scrapped.
He also called for banks to continue lending and said that businesses expect the government to sort out "the appalling state of the public finances".
