Palestine's Fatah movement on Saturday confirmed the Palestinian's right to establish an independent state.
On the Balfour Declaration anniversary, the movement called on the UK to fully recognize the State of Palestine.
The UK-conspired Balfour Declaration was a crime against humanity, Fatah said in a statement.
The movement affirmed its commitment to the historical and natural rights of the Palestinians in their homeland.
The UK full recognition of a Palestinian state on June 1967 borders with Al-Quds as its capital would mark the start to lift the injustice on the Palestinians, the Fatah statement stressed.
The UK must practice pressure on the occupation state to accept a fair resolution to the Palestinian refugees' problem as approved by the international legitimacy resolution, the statement said.
Britain today is in front of a historic responsibility to take part in the world's will in helping the Palestinians in achieving their independence, Fatah confirmed.
