The family of Harry Dunn will meet with the home secretary, Priti Patel, as her office considers extraditing the US suspect charged with causing the teenager’s death by dangerous driving.
Patel is expected to sit down with Harry’s mother, Charlotte Charles, and father, Tim Dunn, just days after the Crown Prosecution Service said they had authorised Northamptonshire Police to charge US citizen Anne Sacoolas.
The CPS said that extradition proceedings had started, noting that the “Home Office is responsible for considering our request and deciding whether to formally issue this through US diplomatic channels.
“Our specialist extradition team will be working closely with the UK Central Authority at the Home Office to do this.”
The Dunn family spokesman, Radd Seiger, tweeted that he was “very much” looking forward to meeting Patel and South Northamptonshire MP Andrea Leadsom “to discuss the tragic loss of Harry”.
Harry, 19, died outside RAF Croughton, in Northamptonshire, when his motorbike was involved in a crash with a car allegedly driven by Sacoolas on the wrong side of the road.
Sacoolas claimed diplomatic immunity due to her husband’s job.
It was only after she left the UK on a military flight directly from the air base that the Foreign Office wrote to the family to say immunity in her case was not valid.
After the Dunn family’s campaign – which included a trip to the White House – the CPS brought the charge, a decision the US government labelled “disappointing” and “unhelpful”.
Following a meeting with the CPS at their London headquarters on Friday, Charles told reporters: “We feel that we have made a huge step in the start of achieving the promise to Harry that we made.
“We made that promise to him the night we lost him, to seek justice, thinking it was going to be really easy.
“We had no idea it was going to be so hard and it would take so long, but we feel it is a huge step towards that promise we made Harry.”
Following the charging decision, the foreign secretary, Dominic Raab, said in a statement: “I welcome the taking of a charging decision, which is an important step towards justice for Harry and towards solace for his family, but it is not the end.”
A statement from Amy Jeffress, Sacoolas’s lawyer, said she had “cooperated fully” with the investigation, adding: “But Anne will not return voluntarily to the United Kingdom to face a potential jail sentence for what was a terrible but unintentional accident.”
Seiger replied: “I know (Ms Jeffress) to be one of the finest and most outstanding lawyers in the USA. Her statement however boggles the mind and is deeply disturbing.
“For Ms Jeffress to seek to undermine one of the most mature, well-developed legal systems in the world, which has fairness at its heart, and which many countries around the world have modelled their legal systems on, is unbecoming of any lawyer, let alone someone of her stature.”
Patel would not be drawn when asked in October if Ms Sacoolas should be extradited.
“It very much seems that the lady in question wants to start cooperating with the discussions and the investigations, and I think that we should support that,” she told the BBC’s Andrew Marr programme.
“We need to ensure that justice is done but obviously that cooperation with this investigation takes place. That is absolutely right.”
