Treasury chief George Osborne sought Monday to ease investor concerns about Britain's vote to leave the
In his first public appearance since Thursday's referendum, Osborne stressed that Britain's economy is in a far better position than it was at the start of the 2008 financial crisis.
"It will not be plain sailing in the days ahead," he said. "But let me be clear. You should not underestimate our resolve. We were prepared for the unexpected."
However, in the first direct reflection of business confidence, a leading business group says 20 percent of its members plan to move some of their operations outside of the U.K. in light of the country's decision to leave the EU.

The U.K. "should only do that when there is a clear view about what new arrangement we are seeking with our European neighbors," he said.
Cameron is expected to chair an emergency Cabinet meeting Monday. U.S. Secretary of State John Kerry is visiting Brussels and London to address the fallout from the vote.
Political turmoil has roiled Britain since the vote as leaders of the government and opposition parties grapple with the question of precisely how the U.K. will separate from the other 27 nations in the bloc.
Cameron, who led the campaign to remain in the EU, has announced he will step down by October.
Opposition leader Jeremy Corbyn is also facing upheaval within his
The vote is also causing a political schism in the U.K. overall. Scottish First Minister Nicola Sturgeon said she would "consider" advising the Scottish Parliament to try to use its power to prevent Britain from leaving the EU. Some 62 percent of Scots voted to remain in the bloc.
Scottish lawmakers might be able to derail Britain's departure by withholding "legislative consent," she said.
