Caerphilly is famous for three Cs: coal, cheese and its mighty castle. It’s also the birthplace of the legendary comedian Tommy Cooper.
And after Thursday’s Senedd by-election, in what was once a Labour stronghold as impregnable as the castle, it’s Plaid Cymru or Reform UK that will have the last laugh.

Mr Gill, who led Reform UK in Wales…
