EU leaders have insisted that the UK must move swiftly to negotiate leaving the organisation, saying any delay would prolong uncertainty, BBC News reports.
European Commission head Jean-Claude Juncker stressed the “Union of the remaining 27 members will continue”.
The UK voted by 52% to 48% to leave the EU, and David Cameron has announced he will step down as PM by October.
He has said it will be up to the new PM to invoke the article that will begin the UK’s withdrawal.
Global stock markets fell heavily on the Brexit news and the value of the pound has also fallen dramatically.
