The first minister’s top adviser is stepping down for health reasons.

Sir Wayne David was appointed as Eluned Morgan’s chief special adviser last December.

The former Labour MP for Caerphilly said there was “no political reason whatsoever” for his resignation.

In a statement the first minister said David had “served Wales with distinction over many decades” and wished him well.

David’s departure means Morgan will need to appoint a third chief adviser since she became first minister last August, and with less than 10 months to go until next May’s Senedd election.

Having governed Wales since devolution began in 1999, current polling suggests Labour face a battle to retain power in 2026.

David was appointed as the first minister’s chief special adviser after ex-Cardiff West Labour MP Kevin Brennan left the position to take a seat in the House of Lords.

Responding to David’s decision to stand down, the first minister said: “Wayne has worked incredibly hard over the past few months, bringing a wealth of political experience to the table at a challenging time.

“He has served Wales with distinction over many decades.

“I wish him well in this next phase of life, which will mean slowing down and putting himself first – not something that comes easily to a man who has dedicated his life to public service in Wales.”

David will officially stand down on 25 July.
