Most British troops were withdrawn to the Suez Canal area in 1947 (although the British army maintained a military base in the area), but nationalist, anti-British feelings continued to grow after the War. Anti-monarchy sentiments further increased following the disastrous performance of the Kingdom in the First Arab-Israeli War. The 1950 election saw a landslide victory of the nationalist Wafd Party and the King was forced to appoint Mostafa El-Nahas as new Prime Minister. In 1951 Egypt unilaterally withdrew from the Anglo-Egyptian Treaty of 1936 and ordered all remaining British troops to leave the Suez Canal.
