Leahy

“It is through these efforts that two former enemies are now partners,” said former Senator Patrick Leahy.

Sir Rob referred in his inquiry appearance to several reports made during his tenure, including "Missed Opportunities", which looked into the circumstances surrounding the deaths of Mr Leahy and Mr R.

Mr Leahy was found unresponsive at the Linden Centre in Chelmsford.

Sir Rob paid tribute to Matthew's mother, Melanie Leahy, who campaigned for more than a decade for a public inquiry, calling her "an exemplary complainant".

Melanie Leahy, whose 20-year-old son Matthew died under NHS care, was joined by fellow campaigners outside the hearing at Arundel House.
