Concerns were first raised about Southern Health after the death of 18-year-old Connor Sparrowhawk, who drowned in a bath at a care home in Oxford in 2013.
Two years after the tragic death of Connor Sparrowhawk and Southern Health NHS Foundation Trust is still not adequately protecting the thousands of people in its care.
For these failings to be allowed to continue is unacceptable. The lack of accountability, at the highest levels of the Trust, is beyond the pale.

They need to see robust action and real accountability and they need to see it now.
