Born in Suffolk Trevor joined what was then the Liberal Party in 1983 having decided it was necessary to campaign for a realistic alternative to Margaret Thatcher's Conservatives and a fairer voting system. He subsequently got involved in local politics where he lived in Essex and served for eight years as a Liberal Democrat District Councillor from 1991 to 1999 including a spell as majority group leader. Trevor subsequently moved to Scotland and had a period campaigning for Charles Kennedy as he lived in his constituency. He is now back in East Anglia and living in Ipswich. He has previously stood for election to Ipswich Borough Council in Bixley ward.
Over the years Trevor has done a variety of voluntary work with Youth Clubs, Community Associations and charities.
