Britain does not have "months to meditate" on the next steps following the Brexit vote, European Commission president Jean-Claude Juncker said Tuesday.

"I have some understanding for the fact that (Prime Minister) David Cameron wants to have some time in order to meditate,"  Juncker told reporters after an EU summit.

But he added: "We want Article 50 (of the Lisbon Treaty formally stating Britain's intention to leave) to be triggered as soon as possible... It has to be speeded up. We don't have months to meditate, we have to act."
