THE chief executive of a health trust criticised for failing to learn from past mistakes will be grilled by MPs today.

Katrina Percy, chief executive of Southern Health NHS Foundation Trust, will face MPs at a session organised by Fareham MP Suella Fernandes.

The organisation has faced repeated criticism for failing to properly investigate the deaths of hundreds of people.

A Care Quality Commission (CQC) report included a warning notice calling on the trust to make improvements "to ensure robust investigation and learning from incidents and deaths, to reduce future risks to patients".

NHS Improvement will also take further action, altering the trust's contract so changes can be made to its management if insufficient improvement is made.

Ms Fernandes said: "This latest warning from the CQC, and the proposed action by NHS improvement are both serious developments in what was already a serious situation.

"I and other MPs from the affected areas want reassurance that proper action is being taken, and I expect we will have some frank questions for Katrina Percy at the meeting."

Ms Percy has so far rejected calls for her resignation, while the trust's medical director Dr Lesley Stevens insisted they had made “real changes” since the Mazars inquiry, which revealed that of 10,306 deaths, only 272 had been investigated between April 2011 and March, 2015.
