A plot to murder Winston Churchill by a radical group in Israel has been revealed in declassified secret documents.

MI5 files show a right-wing group of Jewish extremists planned to send agents to London to kill Churchill and members of his government.

The group called Lehi or 'the Stern Gang', also had in its sights Labour's Ernest Bevin, who was foreign minister for Britain after World War II.

Terror group Lehi was committed to forcing Britain out of Palestine where it held governorship.

The plot to assassinate Churchill was concocted by one of the group's leaders named Eliyahu Bet-Zuri. It was uncovered after a member of the gang was arrested in April 1945.

The group was also responsible for murdering one of Churchill's close friends in Cairo in 1944 – Lord Moyne, a Middle East minister. Bet-Zuri was hanged in 1945 for his role in the murder.

In 1946 the threat of Zionist terrorism to British interests was made starkly clear by the King David Hotel bombing, targeting on the British administrative headquarters for Palestine.

The attack, carried out by militant right-wing, Zionists killed 91 people of various nationalities.
