[1][2][3] His imprisonment in 1929 provoked an enormous outcry, and in Britain, according to Stephen Howe, "probably inspired more left-wing pamphlet literature than any other colonial issue between the wars".

[6] In March 1929, both Bradley and Spratt were arrested as a part of attacks by the British colonial occupation against trade unionism, communism, and the Indian independence movement.

[6] Bradley, Spratt, and many other communists and trade union leaders were charged under section 121A of the Indian Penal Code with "conspiracy to deprive the King-Emperor of the Sovereignty of British India".

[14] In April 1929, communist led protesters held a demonstration at the Marble Arch to Victoria Station in London, which the British police responded to by forcefully removing all ethnic Indians from the area.

[15] The police would commit multiple violent attacks against peaceful Indian demonstrators in England who campaigned for the Meerut prisoners.

[15] These campaigns were highly successful in publicising the plight of Indian republicans and raising public opposition to the sentencing Bradley and his fellow prisoners.

[5] Upon his return to Britain, Bradley was greeted at Victoria station by Shapurji Saklatvala, a leading British communist and the first ethnically Indian person to serve as an MP of the Labour Party.

[14] During the early 1940s when the Communist Party of Great Britain (CPGB) was experiencing a large increase in membership, Bradley played a central role in the day to day running of the party, working closely alongside fellow communist leaders including Palme Dutt, Dave Springhall, and Bill Rust.

[14] After the war, Bradley became the circulation manager for the CPGB's newspaper the Daily Worker in 1946, and then became the National Organiser of the Britain-China Friendship Association.
