[1][2][3] After serving in the Royal Air Force (as a Lancaster bomber rear gunner) during World War II, he became a solicitor.

The Ulster Vanguard movement was formed on 9 February 1972 under Craig's leadership (the Deputy Leaders were the Reverend Martin Smyth and Captain Austin Ardill).

Vanguard held a large rally on 18 March 1972 in Belfast's Ormeau Park at which Craig said "We must build up the dossiers on the men and women who are a menace to this country, because one day, ladies and gentlemen, if the politicians fail, it may be our job to liquidate the enemy".

Craig led the remains of Vanguard in rejoining the Ulster Unionist Party in 1978, but lost his seat at the 1979 general election.

Many historians have agreed that Craig found it difficult to accept that Northern Ireland had to make social and economic reforms.

That is mainly overshadowed due to his early political beliefs and refusal to accept reform and change to Northern Irish society.

[1] After a long period away from public life, Craig died at the Ulster Hospital on 24 April 2011, aged 86, from complications of a stroke he suffered the previous month.
