Journalist, parliamentarian, editor, author and Spectator Australia columnist Peter Coleman has died in Sydney at the age of 90.

He was perhaps the last of his kind, a public intellectual who not only supported the Liberal Party, but also represented it in both the New South Wales and federal parliaments.

Coleman served as a member of the NSW Legislative Assembly from 1968 to 1978, spending his last year as leader of the opposition, then as the member for Wentworth from 1981 to 1986, but he will best be remembered for his journalistic endeavours.
