The Ulster Unionist Party (UUP) retained their majority with Sir Basil McFarland continuing as Mayor of Londonderry.

The elections were postponed from the original February date due to an unusually large number of objections to the list of electors.

On 20 January 1946, the Londonderry Corporation called the election to be held on 10 February and only gave candidates 11 days to file for candidacy.

Collectively, they released a statement condemning the move calling it "electoral manipulation" and encouraged nationalists in the Londonderry Borough Council area to legally object.
