In the 1960s and 1970s Lester was directly involved with the drafting of race relations legislation in Britain. During these periods, he acted as the chair of the legal subcommittee of the Campaign Against Racial Discrimination and was a member of several organisations working for racial equality such as the Society of Labour Lawyers, Fabian Society, Council of the Institute of Race Relations, British Overseas Socialist Fellowship and the National Committee for Commonwealth Immigrants. In 1968, he co-founded the Runnymede Trust think-tank with Jim Rose. He was chairman of the Runnymede Trust from 1991 to 1993.
Lester is a patron of the Family Planning Association, previously called the National Birth Control Committee. He represented the FPA in a contentious case in Northern Ireland where it was widely claimed that the FPA were trying to use strategic litigation to introduce liberalised abortion laws into the country.
Peerage
Lester's peerage was announced on 13 August 1993. He was raised to the peerage as Baron Lester of Herne Hill, of Herne Hill in the London Borough of Southwark on 13 October 1993. Until a sexual harassment complaint was made in February 2018 Lester sat as a Liberal Democrat. On 12 November 2018, the House of Lords Committee for Privileges and Conduct made a recommendation that he be suspended from the House of Lords until June 2022 as a result of a complaint of sexual harassment from Jasvinder Sanghera. On 15 November 2018, on a vote on the floor of the House of Lords, the recommendation of the Committee was not accepted. Members supporting Lord Lester alleged, and the House duly supported the relevant amendment proposed by Lord Pannick QC, that the Commissioner for Standards had failed to comply with paragraph 21 of the relevant Code of Conduct which required her to act in accordance with the principles of natural justice and fairness. After Lord Pannick's amendment was passed, so that the matter was remitted to the Committee, the Senior Deputy Speaker of the House expressed his disappointment at the decision of the House and gave his opinion that the Commissioner had "followed the processes as agreed by the House and that have not been questioned before today.". He also expressed his personal sympathy for the complainant, even though the matter had just been remitted for fair reconsideration of whether her allegations were correct. The fairness of the procedures had in fact been questioned prior to the debate. The report of the Commissioner for Standards addressed various criticisms, without accepting that they were justified. Further, the report itself included as an annex the opinion of David Perry QC which made and analysed various express criticisms of the fairness of the procedures, and the Commissioner had duly responded. Lord Lester of Herne Hill resigned from the House of Lords on 12 December 2018. He said that he lacked the strength or health to continue, after the Committee disagreed with the House on procedural issues of the investigation and renewed the recommendation of his suspension until June 2022. In April 2019 he joined The Independent Group.
Personal life
Lester is the father of Gideon Lester and of Maya Lester QC.
