[4] From 1957 to 1959, Judd was on a Short Service Commission in the Royal Air Force's Education Branch.

He became Secretary-General of the International Voluntary Service in 1960, and is credited with overseeing a significant period of expansion for the organisation.

He became a Member of Parliament in 1966, after gaining Portsmouth West for Labour, in a general election which saw his party win a large majority in the House of Commons.

[2] The following year, he was made Parliamentary Private Secretary (PPS) to the Minister of Housing and Local Government, a role he held until 1970.

He narrowly held his seat at that year's general election, by just 955 votes, although Labour lost power to the Conservatives nationally.

Judd became PPS to the Leader of the Opposition, former prime minister Harold Wilson, holding this role from 1970 to 1972.

[2] When the government lost a vote of no confidence, a new general election was called in 1979, in which Labour were defeated by the Conservatives.

He was again a member of the Council of Europe Parliamentary Assembly from 1997 to 2005, where he became rapporteur on Chechnya (from 1999 to 2004) and visited Grozny several times, for which he was posthumously rewarded with the Order of Friendship by the Chechen government in exile.

His recreations were listed in Who's Who as "relaxing in the countryside, family holidays, enjoying music, opera, theatre and film".
