In 1881 fixed time - limits for questions were introduced and questions to the prime minister were moved to the last slot of the day as a courtesy to the 72 - year - old prime minister at the time, William Gladstone, so he could come to the Commons later in the day . In 1953, when Winston Churchill was prime minister, it was agreed that questions would be submitted on fixed days (Tuesdays and Thursdays). </P>
