Reform MS Member Defects to Plaid Party

Sarah Cooper-Lesadd, one of 34 Reform MSs elected in May's Senedd election, has defected to the Plaid party.

Constituents in Pen-y-bont Bro Morgannwg, Cooper-Lesadd's electoral district, are reacting to the move. The specific nature of these reactions is not detailed in the provided notes.

The Reform party, which saw a significant number of its members elected in the May Senedd election, is now down one representative. The defection brings the total number of Reform MSs to 33. Plaid gains one member, increasing its representation in the Senedd.

Further details regarding the motivations behind Cooper-Lesadd's decision or the immediate political implications of this party switch were not provided.
