At the
1955 federal election, Aston won the seat of
Phillip for the Liberal Party from the incumbent
Australian Labor Party (ALP) MP
Joe Fitzgerald. He was re-elected
in 1958 and joined the Joint Parliamentary Committee on Foreign Affairs, also serving as a
deputy government whip from 1960. However, at the
1961 election he was defeated in Phillip by ALP candidate
Syd Einfeld. He regained Phillip for the Liberal Party at the
1963 election and was reappointed as deputy government whip, replacing
Peter Howson as government whip in 1964. He helped convince foreign minister
William McMahon to make more explicitly pro-Israel statements, following concerns expressed by Israeli contacts. Aston made an official visit to Israel in 1969 and 1971, after which he was described by the
Jerusalem Post as "one of Israel's most faithful and devoted friends in Australia". He was an honorary commander in
Betar, a Zionist youth movement, while his wife was a life governor of the
Women's International Zionist Organization. In 1971 he officially opened the first annual conference of the
Executive Council of Australian Jewry at the new National Jewish Memorial Centre in Canberra.
Speaker of the House Aston was elected speaker of the House of Representatives on 21 February 1967, replacing
John McLeay who had retired after the
1966 election. Prior to his election he had defeated eight other contestants for the Liberal Party's nomination. He remained in office until his defeat at the
1972 election, after which he retired from politics. As speaker, Aston was an advocate for the extension of
question time and for the expansion of the
House's committee system along the lines of the
Senate committees. In his advocacy for the latter he came into conflict with Prime Minister
John Gorton. Aston's proposed procedural reforms were included in a report of the House Standing Orders Committee which he delivered as
ex officio chairman in September 1970. The House did not accept some of the major changes proposed, but did adopt recommendations for shorter speaking times and reduced
quorums. Aston came into conflict with the ALP opposition on a number of occasions. Following his re-election as speaker in 1969, ALP frontbenchers
Kim Beazley and
Clyde Cameron accused him as being a "lackey of the prime minister [Gorton]". In April 1970, Aston
named ALP MP
Gordon Bryant for insulting him, following which Bryant's ALP colleagues crowded around him to prevent his removal by the
serjeant-at-arms. The situation was resolved the following day after intervention from ALP leader
Gough Whitlam. In April 1971, Aston was the subject of a no-confidence motion from the opposition, with ALP deputy leader
Lance Barnard describing him as "arbitrary, capricious, inconsistent and undeniably partisan". The motion was defeated on party lines. One of the most significant incidents involving Aston occurred in March 1971, when journalist
Alan Ramsey shouted "you liar!" at Gorton from the press gallery of the House of Representatives. Whitlam subsequently moved that Ramsey be imprisoned for
contempt of parliament, but this was avoided when Aston assisted Ramsey in drafting an apology. ==Personal life==
