Britain's ruling Labour Party has suffered a dismal by-election in its Welsh heartland, sparking concerns about the future of centrist politics.
The south Wales town of Caerphilly, known for its 13th-century castle, has become a symbol of the challenges faced by establishment parties. A century of Labour Party rule was recently broken in a by-election for the Senedd, the Welsh parliament.
