Born in Muktsar, Punjab, British India, Brar lived and worked in Britain from 1962, first as a student, then as a lecturer in law at Harrow College of Higher Education (later merged into the renamed University of Westminster), and later in the textile business.

Brar has written multiple books on subjects such as communism, Indian republicanism, imperialism, anti-Zionism, anti-colonialism, and the British General Strike.

[1] Adopting positions maintained by Brar and his comrades since the 1960s, the CPGB-ML has been vigorously opposed to all those who work with or in any way endorse the Labour Party since its inception.

He accuses Gandhi and Congress of supporting British imperialism, describing the latter as "the most compromising, cowardly and obscurantist representatives of the India bourgeoisie".

[12] Lalkar, the newspaper edited by Brar, criticises The British Road to Socialism (the programme of the original Communist Party of Great Britain) from its earliest version in 1951 as "un-Marxist"[13] and regards the claim that Joseph Stalin approved it as a "fiction".

These works are a combination of original material and articles previously published in Lalkar and have been translated and distributed internationally by a number of sympathetic communist parties around the world.
