The home secretary has rejected calls from the family of Sir David Amess for a public inquiry into his death in a letter described as “unacceptable” and “insulting” by the murdered MP’s widow and daughter.

In the letter addressed to Lady Julia Amess and Katie Amess, Yvette Cooper said it was “hard to see how an inquiry would be able to go beyond” killer Ali Harbi Ali’s trial and the recently published Prevent learning review.
