The 2021 North Northamptonshire Council election took place alongside nationwide local elections. The election was originally due to take place in May 2020, but was postponed due to the COVID-19 pandemic.[1]
It was the inaugural election for the unitary authority, which was created one month before in April 2021, after the merger of the four existing non-metropolitan districts of Corby, East Northamptonshire, Kettering, and Wellingborough. North Northamptonshire absorbed the functions of these districts, plus those of the abolished Northamptonshire County Council. All 26 wards elect 3 councillors each, resulting in 78 councillors being elected and 40 seats being required for a majority.[2]
A by-election was held to fill the seat vacated by Cllr Annabel de Capell Brooke.[5]
A by-election was held on 2 February 2023 due to the death of Cllr Kevin Thurland.
