The Conservative leader has told Sky News he wants to build on his record and "continue the progress we have made" after he was asked if he would still be prime minister in a year if the Tories were successful.
Beth Rigby put to Mr Sunak that in this Parliament, there have been three prime ministers, five chancellors, five home secretaries and six health secretaries.
Mr Sunak said he could "appreciate people’s frustration" and that "of course, we haven't gotten everything right".
