South Tyneside is a metropolitan borough in Tyne and Wear, centred on South Shields and including Jarrow, Hebburn, Boldon, Cleadon and Whitburn. Its council provides both district and county functions, making it responsible for services including education, social care, housing, planning, waste and local roads.
The borough has held those combined local-government functions since Tyne and Wear County Council was abolished in 1986. Some services are shared across Tyne and Wear, while strategic responsibilities sit with the North East Mayoral Combined Authority.
South Tyneside stretches from the River Tyne to the North Sea coast. Its identity combines shipbuilding and mining Heritage with historic sites including Arbeia Roman Fort, the eastern end of Hadrian's Wall and Souter Lighthouse. Reform's August 2026 Harton hold made the borough one of the party's active council bases.
Reform governs South Tyneside
On 6 August, Reform UK held the Harton ward in South Tyneside with 35.3% of the vote. The result followed the party's May 2026 council victory, which gave it 41 of the authority's 54 seats. For South Tyneside, the by-election was a direct test of whether its new governing party could retain support between full council elections.
The Harton result did not change control of the council, but it preserved Reform's local mandate in the borough. South Tyneside now provides an early case of how Reform's council majority performs while the party holds responsibility for major local services.
