Harry Dunn's mother wants Donald Trump and Boris Johnson meeting
The mother of Harry Dunn has said she hopes to meet the Prime Minister and US president Donald Trump while the pair are in London.
Mr Dunn, 19, died in a road crash in Northamptonshire in August which led to the suspect, Anne Sacoolas, leaving for the USA under diplomatic immunity.
World leaders have been at Buckingham Palace to mark 70 years of Nato.
Mr Dunn's mother, Charlotte Charles, joined crowds outside the palace with a banner featuring a photo of her son.
Mr Dunn's family is campaigning for Mrs Sacoolas to return to the UK to face justice.
Ms Charles said they had emailed Prime Minister Boris Johnson's team requesting a meeting with him and President Trump.
"We had an email back to say that our email was having some attention and consideration," she said.
"It's probably just a standard email, but us as a family would not be able to give up the opportunity of being in London just in case they ever did ring and say we've got a few minutes.
"We don't think it's going to happen but we couldn't sit at home just in case."
Earlier a government spokesman said Foreign Secretary Dominic Raab, who has been heavily criticised by Mr Dunn's parents for his handling of the case, raised the issue with US Secretary of State Mike Pompeo when they met in London.
He added that the UK would continue to press for Mrs Sacoolas to "co-operate fully with the judicial process".

President Trump, who met the family at the White House in October, described them as "lovely people", when he spoke to reporters.
Mr Trump repeated the US position that Mrs Sacoolas had diplomatic immunity but said: "We're trying to work something out."
Mr Dunn was fatally injured on 27 August, when his motorbike was in collision with a car owned by Anne Sacoolas outside RAF Croughton, where her husband Jonathan was an intelligence officer.
Mrs Sacoolas, 42, left the UK claiming diplomatic immunity.
Last week the family began legal proceedings against the Foreign and Commonwealth Office and Mr Raab with the aim of securing a judicial review into Mrs Sacoolas' diplomatic immunity.
