Britain on Tuesday congratulated the Nepalese government and Maoist rebels, who earlier signed a peace deal ending more than a decade of civil war that has claimed at least 12,500 lives.
"The UK congratulates the Government of Nepal and the Maoists on signing their historic Peace Accord," Foreign Secretary Margaret Beckett said in a statement.
"We applaud the commitment of the people of Nepal to build a stable and peaceful future for their country. Their dedication to the cause of peace has prevailed, after a decade of civil war."
"We now look to both sides to make the agreement a reality throughout Nepal. Specifically, the UK again urges both the Government of Nepal and the Maoists to respect and uphold the rule of law."
"We encourage all signatories to the agreement to build consensus and work together with the UN as the country moves towards a new government and new elections. The people of Nepal can count on the support of the UK to help them build a new and better future."
Once deadly foes, the multi-party government and Maoist rebels have observed a cease-fire for more than six months after they co-operated in April to organise mass protests that forced King Gyanendra to restore parliament and end dictatorial rule.
Under the deal, the rebels are to end their "people's war" aimed at overthrowing the monarchy by force, join an interim government and enter parliament.
They must also place their arms and their troops under UN monitoring, and will face mounting pressure to put an end to alleged forced recruitment, including of child soldiers, extortion and political assassinations.
