EU will not hold talks with UK until it triggers Article 50
Germany, France and Italy say the EU will not hold talks with the UK until Article 50 is triggered.
German Chancellor Angela Merkel, French President Francois Hollande and Italian PM Matteo Renzi have agreed there should be no formal or informal talks before Britain triggers Article 50 to withdraw from EU.
Prime Minister David Cameron has previously ruled out triggering Article 50 himself, saying that it must be up to the next Prime Minister and government to do so.
The three European heads of state were attending a joint news conference in Berlin to discuss the UK's exit from the EU.
French President Francois Hollande said at the conference that there is a "price to be paid" for leaving the EU.
Italian Prime Minister Matteo Renzi expressed sadness at Britain's impending exit, but said that this is a "great opportunity to write a new chapter," suggesting that the UK begins the process of leaving.
