Career
A Captain in the Scots Guards, Bullock normally went by his middle name of Malcolm rather than his first name. He was re-elected in the new Crosby constituency at both the 1950 and 1951 general elections, before resigning as an Member of Parliament in October 1953. In February 1954 he was created a baronet, of Crosby in the County Palatine of Lancaster.
Bullock married Lady Victoria Alice Louise Primrose, daughter of Edward Stanley, 17th Earl of Derby and widow of Neil Primrose, in 1919.
They had one daughter, Priscilla, who married the racehorse trainer Peter Hastings, later Peter Hastings-Bass. Lady Victoria died in a hunting accident in November 1927, aged 35.
Bullock died in June 1966, aged 75, when the baronetcy became extinct.
