Angela Merkel vows to use 'all her strength' to keep EU united

German Chancellor Angela Merkel has said she will use "all her strength" to prevent the European Union drifting apart in the wake of Britain's decision to leave the bloc.

In an address to the German parliament before she headed to Brussels to meet with other leaders, Ms Merkel said she expects Britain will want to maintain "close relations" with the EU once it leaves, but she also signalled that it could not expect a business-as-usual approach.
