 The first demonstrations organised by the Fed were the 200,000 strong demonstration in London, parts of which turned into the Poll Tax Riots, and a simultaneous 50,000 strong demonstration in Glasgow on 31 March 1990.Federation leaders Tommy Sheridan and Steve Nally criticised the participants of the riot, and were said to promise to "name names".However, Militant claimed that this was "totally false" and criticised those such as Roy Hattersley who had called for punishment of those involved.
