The Battle for Labour's oldest stronghold:  Wales

On May 7, Labour faces losing some of its oldest heartlands. In Wales, the party has dominated elections for 104 years, but is, according to polls, fighting for third or fourth place against powerful forces on the left and right – Plaid Cymru and Reform. Host Sascha O'Sullivan and POLITICO's political editor Dan Bloom took the train to Newport and drove through South Wales, where the fight is fiercest, to find out how the parties are vying for the top spot in the Senedd, the Welsh Parliament.
