The Southend MP was stabbed to death at a constituency surgery in October 2021 by terrorist Ali Harbi Ali, who had been discharged by terror prevention service Prevent.
Sir David’s family were told by home secretary Yvette Cooper this week that a public inquiry into Prevent failings was not merited.
In a tearful press conference on Monday (March 10), Sir David’s daughter Katie called the decision “an absolute insult”.
Sat in the audience to offer moral support was close family friend Mr Rosindell, who was chosen last year to unveil a statue in Sir David’s honour on Southend seafront.
“It’s an atrocious response,” Mr Rosindell told the Recorder.
“I think it’s completely inadequate. I think she has misjudged the need for what I believe should be a full, independent public inquiry.
“This was the most horrendous crime against a member of parliament. If this doesn’t deserve a public inquiry then what on earth does?
“Both the home secretary and the prime minister should realise that this is not going to go away.
“They longer they push it into the long grass, a very powerful movement of people across the country is going to push for justice.”
Andrew Rosindell at the Westminster press conference over Sir David Amess’s death this week, alongside former Conservative MP Anna Firth, who took over Sir David’s seat after he was killed (Image: Charles Thomson) Miss Amess yesterday slammed both her father’s former Conservative government and the new Labour government for each failing to order an inquiry.
She said the Conservatives had “claimed to be his friend” and were “at his funeral”, yet she claimed they “walked away and abandoned us as a family”.
“This is not a political game where you get to brush things under the carpet and sweep things under the rug in order to negate your wrongdoings,” she said.
“I can see what you are doing and you will not pull the wool over my eyes.”
The family is due to meet prime minister Sir Keir Starmer on Wednesday morning (March 12), where they will again lobby for an inquiry.
In her letter refusing one, Mrs Cooper said there had already been a criminal trial, a Prevent “learning review”, and a coroner had declined to hold an inquest on grounds there were “no additional questions that could be answered through an investigation of this kind”.
