The daughter of Sir David Amess has said the government’s decision to reject a national inquiry into his murder is an “absolute insult” and “betrayal to our father’s memory”.
Katie Amess said the death of her father, who was murdered by Ali Harbi Ali in 2021, had left an “unimaginable void” in her life.
She said the authorities had let her father down “so badly” and that his death had been “brushed under the carpet”.
In a news conference, she urged Home Secretary Yvette Cooper to reverse her decision, saying: “Do not let my father’s murder be forgotten.
“Do not let his death be just another statistic.”
Sir David was stabbed to death by Harbi Ali, an Islamic State (ISIS) supporter, during a constituency surgery at a church hall in Leigh-on-Sea in October 2021.
The killer, who was given a whole-life sentence, had become radicalised by ISIS propaganda and had been referred to the anti-terror programme Prevent before the attack.
A review into his murder found that Harbi Ali was released from the Prevent anti-terror programme “too quickly”, with his case closed five years before the attack following one meeting at a McDonald’s to deal with his interpretation of what is forbidden under Islamic law.
In a tearful statement, Ms Amess accused Ms Cooper of having “strung” the family along for “months” by suggesting she “was working on ways to help us”.
She told reporters: “How can the government justify holding inquiries for other tragic events like Southport and Nottingham and yet refuse to investigate the very system that failed my father?
“Is his life worth less than others?
“Does our family not deserve the truth like other families and to know that what happened will never happen again?”
She continued: “Yvette Cooper has strung us along for months suggesting that she was working on ways to help us.
“However, all she has done is remove the possibility of us being included in the Southport inquiry; instead offering another useless paper review, conducted by a person of their choice.
“I want Sir Keir and Yvette Cooper to know exactly what the consequences are when the very government agencies that are set up to protect people like my dad, and members of the public, fail.
“Doing paper review after paper review into what happened, like what they have done since the day my dad was murdered, is simply not enough.”
Ms Cooper rejected the Amess family’s calls for a public inquiry in a letter to the late MP’s widow and his daughter.
Security minister Dan Jarvis said Sir David’s murder was a “terrible tragedy”.
“In the years since this cowardly attack, there have been several reviews asking how this could have been avoided, and we have seen significant improvements to the Prevent programme as well as stronger protections for MPs,” he said.
“We understand that the Amess family are still looking for answers and we take this incredibly seriously.
“While we do not think a public inquiry would unearth any information that has not already been assessed, the home secretary has confirmed that we will further scrutinise all the reviews that have taken place over the last few years.
“We very much hope this will help the family to get the justice they deserve.”
