Prime Minister John Howard wrote in his autobiography that Abbott considered working on his staff prior to accepting the position with "The Bulletin", and it was on Howard's recommendation that Hewson engaged Abbott. According to Howard, he and Abbott established a good rapport, but Hewson and Abbott fell out shortly before the 1993 election, and Abbott ended up in search of work following the re-election of the Keating Government. He was approached to head Australians for Constitutional Monarchy (ACM), the main group organising support for the maintenance of the Monarchy in Australia amidst the Keating Government's campaign for a change to a republic. Abbott renounced his British citizenship in 1993. Between 1993 and 1994, Abbott served as Executive Director of ACM. According to biographer Michael Duffy, Abbott's involvement with ACM "strengthened his relationship with John Howard, who in 1994 suggested he seek pre-selection for a by-election in the seat of Warringah". Howard provided a glowing reference and Abbott won pre-selection for the safe Liberal seat.
