Before entering Parliament, Jones was active in Labour politics, serving as chairman of the
Wood Green Constituency Labour Party and secretary of the Rhondda West Constituency Labour Party from 1965 to 1967. Having served as Thomas's political agent, Jones was selected as the Labour candidate for the resulting
by-election. During his parliamentary career, Jones established one of the safest Labour seats in Britain, achieving a majority of more than 38,000 votes in the
1979 general election.
Ministerial career Following Labour's victory in the
October 1974 general election, Jones was appointed as
Parliamentary Under-Secretary of State for Health and Social Security in
Harold Wilson's government on 18 October 1974. In this role, he succeeded
Robert Brown and served until 12 June 1975, when he was succeeded by
Michael Meacher. On 12 June 1975, Jones was promoted to
Parliamentary Under-Secretary of State for Wales in the
Welsh Office, serving under Secretaries of State
John Morris and later during the
James Callaghan government. He held this position until Labour's defeat in the
1979 general election on 4 May 1979. As Parliamentary Under-Secretary for Wales, Jones had special responsibility for housing, land reclamation, local government and devolution during a crucial period for Welsh governance.
Opposition years Following Labour's defeat in 1979, Jones was appointed as Principal Opposition spokesman on Welsh affairs, effectively serving as
Shadow Secretary of State for Wales under
James Callaghan and later
Michael Foot. He was made a
Privy Councillor in 1979, granting him the style "
The Right Honourable". Jones also served as secretary to the Welsh Parliamentary Labour Party during this period. He continued in this role until his death in March 1983, shortly before the
1983 general election. == Personal life ==
