British foreign minister William Hague said on Friday that a peaceful solution in Syria has to be without Bashar al-Assad.
During a visit to Kuwait, Hague said: "We have always been clear that any peaceful solution in Syria must be without president Al-Assad."
Hague, who met his Kuwaiti counterpart, said: "After this number of deaths and destruction it is impossible to imagine that a regime, which oppressed its people, can remain in power."
According to the Syrian Observatory for Human Rights, around 140,000 Syrians have been killed during the 33-month conflict in Syria. The clashes have also cost the country billions of dollars of destruction across Syria.
The British foreign minister, whose country supports the Syrian opposition, said: "It is impossible to imagine Al-Assad staying at the forefront of Syria's future."
