The family of a South Norwood man who died after excessive force and restraint was used at a psychiatric hospital were "upset and confused" as they watched a Tory MP deliver one of the Commons' longest speeches in recent years.

Cries of "shame" were heard in the chamber last week as a Bill known as Seni's Law was blocked due to the efforts of Philip Davies (Shipley) and former minister Sir Christopher Chope.

Olaseni Lewis was 23 when he died after being restrained by up to 11 police officers at Bethlem Royal Hospital in Monks Orchard Road on August 31, 2010.

Since then, Olaseni's family and Croydon North MP Steve Reed have fought tooth and nail to introduce a new law to make sure "nothing like what happened to Seni happens again."

But on Friday (June 15), those plans were put on hold.

Mr Davies addressed more than 100 amendments put to the Bill during report stage by MPs during an address which lasted almost two-and-a-half hours.

The length of his speech meant the Bill was unable to pass through its final Commons stage, something Mr Reed was frustrated by.

"It was a bit of silly game playing by the MPs," he said.

"It's very disappointing that they spoke for nearly 2.5 hours to delay the progress."

The Bill's aims include ensuring the use of force in relation to patients in the units is better governed and requiring police to wear body cameras while carrying out restraint unless there are legitimate operational reasons for not doing so.

Also in attendance on the day was Olaseni's family.

Mr Reed said it was unfair what they had to be put through.

"They were upset that the MPs were taking so long with their speeches and I wasn’t at all happy they were made to sit there and listen to it," he said.

"But since then there has been such anger against the MPs that I don't think they will repeat the performance next time.

"Now we are talking to MPs one by one to make sure we have enough numbers to get it through next time."

Mr Davies insisted the Bill would not be lost, and would progress on a future Friday sitting in a "better state" once the Government has looked at amendments.

He pushed for two specific changes to be accepted by ministers, including outlining the roles, responsibilities and procedure in the event of police involvement as part of training offered to staff working in mental health units.

He said of his proposed changes: "They go to the very heart at what happened to Mr Lewis on that terrible occasion, which would actually give the training to staff to make sure those things couldn't happen again."

Debate is expected to resume on July 6 where Mr Reed hopes it clears the Commons and moves to the Lords.
