UK will do `whatever is necessary` to protect its economy after Greek vote

London: Britain will do "whatever is necessary to protect its economic security", a government spokesman said Monday after Greeks voted overwhelmingly against austerity in a referendum that could send them crashing out of the eurozone with unknown consequences.

"This is a critical moment in the economic crisis in Greece," a Downing Street spokesman said. "We will continue to do whatever is necessary to protect our economic security at this uncertain time. We have already got contingency plans in place and later this morning the Prime Minister will chair a further meeting to review those plans in light of yesterday`s result."
