The mother of Harry Dunn has accused Foreign Secretary Dominic Raab of 'effectively blackmailing' her into dropping a High Court quest for the truth about her son's death – with the threat of bankruptcy.
Harry, 19, died after former US spy Anne Sacoolas crashed into him as he rode his motorbike outside RAF Croughton in Northamptonshire last August.
The Foreign Office (FCO) has warned his family they will pursue them for legal costs if they try to overturn the Government's decision to grant Sacoolas diplomatic immunity after the crash.
Dunn's mother, Charlotte Charles, and his family want the courts to render unlawful advice given by the FCO to Northamptonshire Police in the wake of the crash that insisted Sacoolas had diplomatic immunity as the spouse of a diplomat.
But Harry's family say they risk financial ruin if their legal bid is unsuccessful and have today made a public appeal to 'crowdfund' their judicial review attempt against the Foreign Secretary that will be heard in the High Court in May.

They have hired leading human rights lawyer Geoffrey Robertson QC and his team to fight on their behalf. The Government has instructed leading silk Sir James Eadie QC to quash the action, risking costs of more than £100,000.
The astonishing 'blackmail' blast comes as the The Mail on Sunday can reveal for the first time the secret treaty drawn up in 1995 between Britain and the United States that Mr Raab admitted to MPs was an 'anomaly', yet puts Mrs Sacoolas above the law.
The treaty, a secret exchange of letters between FCO Ministers and US diplomats never before seen or scrutinised by Parliament, states that 'immunity from criminal jurisdiction' was not to be granted to employees at RAF Croughton – a secret US listening station.
The US government claimed Sacoolas's husband worked at the facility, so while he would have not had diplomatic immunity for the crash under this treaty, his spouse and families would because they are not mentioned in it.
