Sir Keir Starmer said he was “deeply disappointed” by Labour’s loss in the Welsh Parliament by-election and conceded the ruling party “clearly need to do much more”.

The Prime Minister said the UK and Welsh administrations need to “reflect and regroup” after Friday’s result, which saw Plaid Cymru sweep to victory with Reform UK coming second.
