EU Brexit 'sets dangerous precedent'

One of Germany's top businessmen says Europe should not negotiate with David Cameron over his desire to change Britain's relationship with the EU as it could "set a dangerous precedent".

Volker Treier, who is the deputy chief executive of Germany's chamber of commerce and industry, was speaking on the eve of the British prime ministers first meeting with Angela Merkel since his new government formally confirmed it will hold a referendum on EU membership.

Dr Volker Treier told the BBC there should be no negotiations with Britain while it is threatening a Brexit.
