Treasury chief George Osborne has sought to calm nerves in the markets, as investors worry about the consequences of Britain leaving the European Union.

In his first public appearance since the vote to leave the bloc Thursday, Osborne tried to reassure markets shaken by the result, saying "our economy is about as strong as it could be to face this challenge."

Yet, he acknowledged it would not be plain sailing in the days ahead.

The pound fell in Asian markets amid fears of the consequences of the vote. Political turmoil has roiled the country, as the leaders grappled with the question of how precisely the country would separate Britain from the other 27 nations in the bloc.

Germany, Britain and France will be meeting to discuss the decision.
