[1] Stallard was Member of Parliament for St Pancras North from 1970 until the constituency was abolished in boundary changes at the 1983 general election.

In both the February 1974 and October 1974 general elections, his Conservative Party opponent was future Prime Minister John Major, who was making his debut as a parliamentary candidate.

After being passed over for selection for a re-drawn seat of Holborn and St Pancras in the 1983 general election in favour of Frank Dobson, the younger Labour candidate from Holborn and St Pancras South, the other half of the merged constituency, Stallard was appointed to the House of Lords.

He was created a life peer as Baron Stallard, of St Pancras in the London Borough of Camden, on 7 September 1983.
