The UK asks the Egyptian Armed Forces to support a national dialogue and for opposition to consider talks with President Morsi ahead of a looming 4:30pm deadline, by which the military announced they will take over.

"We [UK government] continue a dialogue with all sides," and urge the Muslim Brotherhood to participate in building a democratic process, a UK Foreign Office spokesman tells Ahram Online.

"We also urge the Egyptian opposition to participate constructively in a national dialogue to ensure unity," the source continued, meaning the opposition should be willing to talk with the Brotherhood-fielded president. 

"We have reiterated those messages with the Egyptian military," the spokesman confirmed. 

"We have worked with President Morsi and the Muslim Brotherhood over the past year to support Egypt’s transition to democracy," he revealed.

"We have urged them to build an inclusive democratic process which strengthens key institutions and treats all Egyptians equally," said the spokesman.

The UK said the right of protest "should be guaranteed as a key part of democracy in action," adding it is "important all sides avoid violence and seek peaceful solutions."

UK Prime Minister Dave Cameron has repeatedly said his country will do its best to assist.

"We remain committed to supporting political transition and strengthening democracy in Egypt, which should include dialogue between all parties which allows all Egyptians’ voices to be heard," the Foreign Office spokesman said.

Egypt has been in a process of political transition after the January 25 Revolution in 2011. 

Since Sunday 30 June massive protests described by international media as the largest in history have been demanding the Brotherhood-fielded President Morsi leave office. Pro-Morsi supporters have also been demonstrating, although in smaller numbers than the masses of anti-Morsi camp.
