Representatives of European Union's founding six states have called for the UK to end its delay in starting the Brexit process.

Following an emergency meeting in Berlin between the German, French, Belgian, Italian, Dutch and Luxembourgish governments representatives from several countries made their position on when the United Kingdom should begin exit negotations.

German foreign minister Frank-Walter Steinmeier called on the British government to initiate Brexit "as soon as possible".

He said on Saturday: "We join together in saying that this process must begin as soon as possible so we don't end up in an extended limbo period but rather can focus on the future of Europe and the work toward it".

Steinmeier said he does however "respect" the referendum result.

He continued: "We understand and respect the result (of the referendum) and understand that Britain is now concentrating on Britain.

"But London has a responsibility toward more than just Britain. We must now be allowed to focus on the future of Europe and that means that after the decision taken in Britain, the process by which we negotiate Britain's exit must begin.

His French counterpart Jean-Marc Ayrault appeared to call on David Cameron to resign immediately as opposed to his plan to formally resign and be replaced at the Conservative party conference in October.

Ayrault said: "A new prime minister must be designated, that will take a few days".

On Friday, David Cameron stated the new Prime Minister would invoke Article 50 of the European Union's Lisbon Treaty and begin the Brexit negotiations.

The whole process could take two years.
