Harry argues he ‘has been singled out for inferior treatment’ after ‘stepping back as working royal’
Mr Langdown took a seat in the public gallery behind his boss.
Harry believes he is entitled to armed bodyguards, paid for by the British taxpayer, and is fighting a 2020 decision to reduce the level of security after he and Meghan Markle stepped back from life as working royals and emigrated to the United States.
He has expressed safety concerns about returning to the UK with his wife and children.
It came after landed in the UK just before King Charles III jetted off to Italy for a historic four-day state visit.
The King and his son are also believed to have differing views over Harry’s decision to pursue his legal fight with the Home Office, which has cost the British taxpayer £500,000 so far.
Harry has been taking legal action in the UK over a decision made by the Executive Committee for the Protection of Royalty and Public Figures (Ravec) in February 2020 over the level of protection he should receive when in the country.
The High Court previously heard that his ‘status’ had changed as a result of no longer being a ‘full-time working member of the Royal Family’.
But Harry has argued his children, Prince Archie and Princess Lilibet cannot ‘feel at home’ or ‘safe’ in the UK unless his police protection is fully restored.
His legal fight comes as the Charity Commission announced it had launched an investigation into Sentebale, the charity he founded, amid a bitter boardroom rift between Harry and chairwoman Dr Sophie Chandauka.
She has accused Prince Harry of ‘harassment and bullying’ – a claim that is denied.
