By Michael Holden and Elizabeth Piper LONDON/BRUSSELS (Reuters) - European leaders told Britain on Tuesday to act quickly to resolve the political and economic chaos unleashed by its vote to leave the European Union, a move the IMF said could put pressure on global growth. British Finance Minister George Osborne, whose attempt to calm markets had fallen on deaf ears on Monday, said the country would have to cut spending and raise taxes to stabilise the economy after a third credit ratings agency downgraded its debt. European countries are concerned about the impact of the uncertainty created by Britain's vote to leave on the 27 other EU member states.
By Gabriela Baczynska and Robert-Jan Bartunek BRUSSELS (Reuters) - Outgoing Prime Minister David Cameron faced irritation, pity and scorn on Tuesday from European Union leaders and lawmakers who pressed him to give early notice of Britain's intention to leave the bloc after last week's lost referendum. Shortly before he arrived in Brussels for a summit dominated by Brexit, the European Parliament adopted a non-binding resolution after angry exchanges demanding that London activate the EU treaty's voluntary exit clause as fast as possible. "Waiting for several months, as has been announced by you, Prime Minister Cameron, and taking the destiny of our entire continent hostage purely for internal party political reasons would be totally unacceptable," European Parliament President Martin Schulz told the British leader in the summit session.
