Query: When did Britain announce plans to withdraw from Palestine?
Context: The matter was complicated by large numbers of Jewish refugees seeking to be admitted to Palestine following the Holocaust, while Arabs were opposed to the creation of a Jewish state. Frustrated by the intractability of the problem, attacks by Jewish paramilitary organisations and the increasing cost of maintaining its military presence, Britain announced in 1947 that it would withdraw in 1948 and leave the matter to the United Nations to solve. The UN General Assembly subsequently voted for a plan to partition Palestine into a Jewish and an Arab state.
