Harry Dunn's family met with Esher and Walton MP and Foreign Secretary Dominic Raab again yesterday (December 17) and said they had been given "hope" in their pursuit of justice.

19-year-old Harry Dunn was killed when his motorbike crashed into a car thought to be driven by Anne Sacoolas, the wife of a UK-based US diplomat, outside RAF Croughton on August 27.

Raab, who retained his Esher and Walton seat at last week's General Election, met with Harry's parents Tim Dunn and Charlotte Charles on Tuesday.

In a statement they said they had been given new "hope" after a more "open and friendly" conversation with the Esher and Walton MP.

The family previously criticzed Raab's response to Harry's death during the campaign.

Mrs Sacoolas, who is the primary suspect in Harry's death, left the UK for the US under diplomatic immunity soon after the collision where Harry was killed.

On Tuesday evening, Raab urged Mrs Sacoolas to "do the right thing" and cooperate with UK law enforcement's investigation into Harry's death.

"We are united in our determination to get justice for Harry," Raab said.

"The Government will do everything it can.

"I also reaffirmed my commitment to conclude the review of the arrangements at RAF Croughton by the end of the year to ensure they cannot be used in this way again.

"I appeal to Anne Sacoolas herself to do the right thing.

"If there is a charging decision from the Crown Prosecution Service, I urge her to come back to the United Kingdom and cooperate with the criminal justice process," he added.

Harry's mother Charlotte was reportedly left "utterly devastated" by watching footage of Sacoolas reversing out of driveway in Virginia while in the US.

Family lawyer and spokesperson Radd Seiger commented on Raab's reaction to the footage of Sacoolas "getting on with her life".

"Like the rest of us, he just shook his head, none of us can understand it, because it's inexplicable," Seiger said.

The family's spokesman said Tuesday's "warm" meeting with Raab had covered a range of issues, with the two sides agreeing to "improve" communication.

"One of the things that came across loud and clear for us which hadn't come across before is that both Andrea Leadsom (Business Secretary and MP for Northamptonshire South) and the Foreign Secretary Dominic Raab would like this lady to come back too, and that's not something that we had heard," Seiger said.

"He shared with us that he needs to be very careful with his words and what he says, he doesn't want to get hopes up.

"But he assured us that he's doing absolutely everything he can to give this family the justice that they need and deserve," Seiger added.
