Proposals for "Seni's Law" to reform the use of force in mental health units has passed its first Commons hurdle.

A Private Members' Bill from Croydon North MP Steve Reed received an unopposed second reading from MPs.

His Mental Health Units (Use of Force) Bill has been inspired by the case of Olaseni Lewis, who was known as Seni to friends and family.

The 23-year-old from South Norwood died in September 2010, days after he fell unconscious while being restrained by 11 Metropolitan Police officers at Bethlem Royal Hospital in Beckenham.

Mr Reed told MPs a coroner had concluded earlier this year that there is a risk of similar deaths in the future unless action is taken.

Mr Reed paid tribute to Mr Lewis' parents.

"They told me they don't want Seni's death to be in vain," he said.

"They don't want any other family to suffer as they have suffered.

"I say to this House now, and to his parents, Seni Lewis did not die in vain.

"We can honour his memory by making sure no one else suffers the way he did and by making our mental health services equal and safe for everyone.

"I dedicate this Bill to Seni Lewis. This is Seni's Law, and I commend it to the House."

Just days before "Seni's Law" passed the first hurdle, Leader of the Labour Party Jeremy Corbyn posted a video on Twitter backing the bill.

"Seni Lewis from Croydon, was only 23 when he died in a seclusion unit whilst held down on the ground," he said.

"Too many mental health patients have died after being physically restrained with unacceptable levels of force and violence.

"Seni’s Law will open up the mental health services to the scrutiny and accountability that’s needed to save lives."

The private members' bill would require police officers to wear body cameras while carrying out restraint unless there are legitimate operational reasons for not doing so.

It would standardise data on recording the use of force and ensure every mental health provider has a policy in place regarding it.

Any non-natural death in a mental health unit would automatically trigger an independent investigation under the plans.
