Britain's ruling Labour Party has suffered a dismal by-election in its Welsh heartland, with the south Wales town of Caerphilly being a notable example.
The town, known for its 13th-century castle, has seen a century of Labour Party rule come to an end in a by-election for the Senedd, the Welsh parliament.

By-elections give voters a "free hit" on the ruling party.
