Foreign Secretary William Hague is set to hold talks with key figures in Egypt in the wake of President Hosni Mubarak's ejection from power.
Mr Hague will meet Field Marshall Mohammed Tantawi, head of the Supreme Council for Armed Forces, and prime minister Essam Sharaf.
He will also discuss the latest developments in the region with the secretary general of the Arab League, Amr Moussa.
Speaking ahead of his visit, Mr Hague said: "As a result of the extraordinary events of the recent months and the courage and determination of the Egyptian people, Egypt today stands ready to achieve the transition to a democratic government that meets the aspirations and commands the respect of all Egyptians.
"We welcome the actions being taken by the authorities to move towards this - including the reorganisation of the State Security organisation - but there is still more to be done.
"The success of the Egyptian transition is critical to that of the Arab Spring.
"The Egyptian people have led the way. So it is even more important that they are able to overcome the political and economic challenges they now face. That is why in addition to generous support from the EU, Britain will continue to offer assistance through our Arab Partnership.
"I also look forward to wide-ranging discussion on a range of regional issues including the situation in Libya and Syria, and the latest developments on the Middle East peace process."
