🔴 Labour’s Unprecedented Collapse

Labour’s vote share plummeted amid widespread criticism of its economic management and failure to address regional disparities. Deputy First Minister’s admission of likely defeat preceded Morgan’s resignation speech, where she acknowledged the need for "radical change" in the party. The results were worse than even the most pessimistic predictions, with Labour losing over 1,000 council seats across England and Wales, marking a historic low for the party.BBC News+3

🗳️ Electoral System Amplifies Political Shift

The new closed proportional list system played a pivotal role in reshaping the political landscape, better reflecting voter intentions. Analysts noted that the system allowed smaller parties like Reform UK and the Greens to gain representation while accelerating Labour’s decline from 30 seats in 2021 to single digits. This electoral overhaul facilitated Plaid Cymru’s historic gains and underscored the broader shift in Welsh politics.The Independent+3
