The mother of a teenager who died while under the care of a troubled mental health trust has told ITV News it is "obscene" the trust's former chief executive will receive a £190,000 payoff.
Katrina Percy resigned as chief executive in August over Southern Health NHS Trust's failure to investigate hundreds of deaths but went straight into a role specially created for her at the same trust.
She will now receive a £190,000 settlement deal - the equivalent of one year's salary - after agreeing to step down from the new advisory role.
Dr Sara Ryan, whose 18-year-old son Connor Sparrowhawk drowned in a bath at an NHS assessment and treatment unit after an epileptic seizure, said she was "disgusted" by the payoff.
"I think it's good that she's gone, but the payoff is obscene," she told ITV News. "How can the NHS afford such payoffs for people who have failed?"
The trust hit the headlines after it was revealed it failed to investigate the unexpected deaths of hundreds of its patients between 2011 and 2015, including Mr Sparrowhawk, who died in 2013.
In October 2015, a jury inquest ruled that neglect contributed to his death.
But in April, inspectors concluded the trust was still failing to protect patients from risk of harm.
Care Quality Commission inspectors found robust arrangements to probe incidents, including deaths, had not been put in place, resulting in "missed opportunities" to prevent similar events.
Dr Ryan, who received an abusive voicemail message in May after her public criticism, said she was "not optimistic that things will change at the trust" and criticised Health Secretary Jeremy Hunt for a lack of action.
"It's scandalous that it's taken this long," she said. "It's shameful that Jeremy Hunt has done nothing - it's all been down to the families."
Southern Health NHS Foundation Trust said in a statement it had "listened to" and "reflected" on correspondence from the public, patients and families expressing their concerns over Ms Percy's continuing role.
A spokesman for NHS Improvement said Ms Percy's role as chief executive had clearly become untenable but there had been "no legal grounds" on which to dismiss her.
Her payoff comprises of six months' pay in lieu of notice and an entitlement to a further six months' pay as part of the settlement, both of which must be repaid should she get another role with the NHS within 12 months.
