Labour’s majority on Swindon Borough Council is now the largest it has been since the 1990s.
Keir Starmer’s party won 14 of the 20 seats that were up for grabs in this year’s election, gaining nine, and the Conservatives won the other six.
The unitary authority now has 41 Labour councillors, 15 Tories and one Liberal Democrat.
Until Labour took control in last year’s elections, the Conservatives had enjoyed a majority since 2004.
Council leader Jim Robbins said it was ‘great to get so many gains’.
He added: ‘It is humbling to receive such support and we are determined to build the fairer, greener, better Swindon that the residents deserve.’
Elsewhere, Conservative Ben Houchen has been re-elected as Tees Valley mayor.
Meanwhile, former Prime Minister Boris Johnson was turned away from his local polling station after failing to bring valid photo ID, and the veterans minister apologised to a former soldier who was unable to vote using his veteran card as identification.
