THE Foreign Office asked Northamptonshire Police to delay telling Harry Dunn’s family that his killer had left Britain, Dominic Raab has admitted.

The teenager was run over by Anne Sacoolas, the wife of a US diplomat, who was driving on the wrong side of the road outside a US spy base in Croughton, South Northamptonshire on August 27.

Mr Raab admitted that the Foreign Office had asked for a delay of “a day or two, no more than that” to make sure they were clear on their plans going forward.

He said: “The police are in charge of liaising with the family [over] this very difficult and tragic case.

“They asked the Foreign Office for advice and one of our officers said it would be useful to have a day or two, no more than that, just to make sure we were clear on what we’d be doing going forward, and just to make sure that ministers could be consulted.”

Ultimately, the family were kept in the dark for 10 days after police found out Ms Sacoolas had left Britain.

Labour’s shadow foreign secretary Emily Thornberry is demanding an inquiry into the case.

She said: “It now looks increasingly clear that the Foreign Secretary and his officials have something to hide in terms of how they responded to this dreadful tragedy, why they allowed Anne Sacoolas to leave the country, and why they delayed informing Harry Dunn's family of her departure.

“We need an urgent parliamentary inquiry to uncover who did what in this case, who took the decisions, when they were taken, and why.”
