By the end of 1975, Lewis' image was badly damaged and he soon lost the confidence of his party. Sentiment was growing in favour of replacing him with Sir Eric Willis. At a caucus meeting on 20 January 1976, parliamentary backbencher Neil Pickard called a spill motion, which was carried 22 votes to 11. Lewis opted not to try to regain his post, leaving Willis to take the leadership unopposed. Lewis's term as Premier came to an end on 23 January 1976, his 54th birthday. Lewis was the only non-elected non-Labor premier who did not take the Coalition into an election.
