A governor at a scandal-hit NHS trust where a teenager drowned in a bath resigned on Friday because his council has achieved "nothing at all".
Mark Aspinall, a governor at Southern Health, accused colleagues of being "apathetic" and "intransigent", and said the Trust's council was "weak or unable to act".
Mr Aspinall, whose resignation follows chairman Mike Petter's resignation, described himself as "hamstrung" by the "constant barrage of critical news" hitting the Trust.
"I don't feel that the Council has achieved anything at all in the period that I have been a member", he wrote.
"I had hoped that we would be able to work well together to deliver for our patients and communities but sadly, there is more drum-banging, soap-boxing and agenda pushing taking place than anything else".
A scandal-hit NHS trust where a teenager drowned in the bath is still failing to protect patients from risk of harm, a watchdog has found.
Mike Petter stepped down ahead of a CQC report into failings at the trust - which has been criticised for not properly investigating deaths.
