He was decisive in the move to oust the Hyndman national chauvinist current in the BSP in 1916 and also took part in founding of the Communist Party of Great Britain.

After winning a London County Council scholarship, Andrew Rothstein studied History at Balliol College, Oxford[1] and served in the Oxfordshire and Buckinghamshire Light Infantry and Hampshire Yeomanry from 1917 to 1919.

He was a corporal when he discovered that his unit was about to be sent to Archangel, the Russian port where British troops had been sent to assist the Tsarist forces resistance to the new Soviet government, led by the Bolsheviks.

This was the first of many rebellions and mutinies in the British Army against the intervention in Russia, involving up to 30,000 troops at its height, the history of which was later documented by Andrew Rothstein in his Soldiers' Strikes of 1919.

[citation needed] Rothstein met Sylvia Pankhurst on several occasions and said that he thought her "energetic and sincere but in a one-sided way, she always had a bunch of devoted women around her but often would think nothing of intercepting propaganda material being brought for my father and printing them as articles in her own paper.

Twenty years later, when he met a former junior dean from those days, who told him that the Foreign Secretary, Lord Curzon had personally intervened in his case.

Rothstein was "utterly against" the new line [citation needed] but found himself appointed as deputy head of the Anglo-American department of the Red International of Labour Unions and served in the post for 18 months, based in Moscow.

Andrew Rothstein was President of the Foreign Press Association, from 1943 to 1950 and, after the war, was the London correspondent of Czechoslovakian trade union paper, Prace, a post he held until 1970.

From 1946, he lectured at London University's School of Slavonic and East European Studies but was dismissed on spurious grounds in 1950 in an affair that had the feel of a McCarthyite purge about it.
