Intelligence agencies could not prevent the murder of soldier Lee Rigby despite his killers featuring in a total of seven error-filled operations before the attack, a parliamentary watchdog has found.
The Prime Minister says he will meet Fusilier Rigby's family if they wanted to see him.
The family's MP Liz McInnes asked for the Prime Minister to "arrange a meeting with them if necessary" and to "endeavour to ensure that all their questions are given full answers".
Mr Cameron said: "A police liaison team is still working with the family, and they should know that whatever meetings they want, they can ask for and they will get."
The family of Lee Rigby say they want to meet the Prime Minister to seek answers about his death.
