The All Britain Anti Poll Tax Federation, commonly known as "the Fed", was an organisation in Great Britain to co-ordinate the activities of local Anti-Poll Tax Unions (APTUs) campaigning against the Poll tax (officially the "Community Charge") brought in by Margaret Thatcher's Conservative government in 1989 (Scotland) and 1990 (England and Wales). The BBC technicians' union, Broadcasting and Entertainment Trades Alliance (Beta) affiliated to the Fed, unlike many other trade unions.
