His last term in office was marked by tension between the NSW and Victorian Governments and a view that Askin was getting out of touch with the voters. Late in 1974, Askin announced his resignation, and his last intervention was to support his Minister for Lands, Thomas Lewis, in his bid to be Askin's successor instead of the Deputy Leader and Minister for Education, Sir Eric Willis. It was reported that Lewis had offered to upgrade Askin's knighthood from Knight Commander (KCMG) to Knight Grand Cross (GCMG) of the Order of St Michael and St George, while Willis was uncommitted. Askin retired from politics in January 1975 and was succeeded by Lewis as Premier. On 14 June 1975 he was elevated to Knight Grand Cross, for his service as Premier. His resignation began a turbulent year for the government. Lewis was ousted in a party room coup by Willis in 1976, but Willis only lasted four months before losing the 1976 election to Labor, ending the longest unbroken run for a non-Labor government since World War I.
