In a statement, the North Wales Health Alliance campaign group said: “Trevor Purt’s departure is an opportunity for the health board to re-engage with both staff and the general public, who have grave concerns about the way health services in the North are being run.
"His time here will be remembered as one of centralising and downgrading services and failing to be open and transparent with the community.
“But the problem goes much deeper than just one man or one position. The health board and Welsh Government has to accept that their direction of travel has to change or we will see further problems emerge.”
