Jenkins was involved in the Victory for Socialism group opposed to the 1956 Suez War and had been a supporter of CND and nuclear disarmament since its foundation in 1957.

[3] Jenkins won Putney, where he and Marie had moved, in the 1964 election, quickly becoming involved in the Tribune Group of MPs.

So skilfully did he exploit the informal procedures of the Upper House that a limit had to be imposed on the number of questions a peer could ask each day.

[1] Jenkins continued to write pamphlets and radio plays, serving on the board of the Royal National Theatre.

His parliamentary correspondence and speeches continued to be typed on the same Amstrad 256 until he entered a care home at the end of his life in 2004.

[6] His anti-nuclear activities before the formation of CND led to rightwingers within the Labour Party attempting to block him as a parliamentary candidate.
