BBC News - Cameron warned UK might quit EU over president - Spiegel
German magazine Der Spiegel says British PM David Cameron warned that the UK could leave the EU if Luxembourg ex-PM Jean-Claude Juncker became president of the European Commission.
It reported Mr Cameron as saying that the appointment could destabilise the UK government and bring forward referendum plans on EU membership.
Downing Street has not yet commented.
