Alan John Williams (born 14 October 1930, Caerphilly) is a Welsh politician and Labour Member of Parliament for Swansea West since the 1964 general election.
Williams served under Harold Wilson as Under-Secretary of State for Economic Affairs from 1967 until 1969 and then as a Parliamentary Secretary at the Ministry of Technology until 1970 when Labour lost power. When Labour were returned to power at the February 1974 general election, Williams was made Minister of State at the Department of Prices and Consumer Protection, serving until Wilson left office in 1976. The new Prime Minister, James Callaghan, then appointed him as Minister of State at the Department of Industry in which post her served until Labour left power in 1979.
Williams was made a Privy Counsellor in 1977. He has been on the backbenches since 1989, and chair of the Liaison Committee since 2001. He is a Eurosceptic and was opposed to the devolution settlement that established the National Assembly for Wales.
Following the retirement of Tam Dalyell at the 2005 general election, Williams became the MP with the longest continuous service in the House, earning him the title of Father of the House. As a result he had the distinction of asking the very last question to Tony Blair at Prime Minister's Questions before he left office.
Williams is the last parliamentary survivor of those who were elected in Harold Wilson's 1964 election win. He has stated his intention to retire from Parliament at the next general election.
