The Court of Appeal today heard Prince Harry's case for appeal against a High Court ruling that backed a move to decide on security for his visits to the UK on a case-by-case basis.
The Duke of Sussex arrived at court shortly after 09:30 BST and sat at the centre of the room throughout proceedings.
He has previously emphasised the importance of safety for his children - saying he wants them to feel at home in the UK.
Harry's barrister, Shaheed Fatima KC, said he had been "singled out" for inferior treatment - as she argued the Royal and VIP Executive Committee (Ravec) did not follow its standard procedures in getting expert analysis on the risks facing the duke before making the decision to change his security arrangements.
Last year, the High Court ruled that there had been no unlawfulness in Ravec's decision.
In written submissions for today's hearing, the government's barrister said the appeal case puts forward arguments based on "small parts of the evidence" - he said it involves "a continued failure to see the wood for the trees".
The hearing will resume for a second day tomorrow with more from the government's case, with a final judgement due in writing at a later date.
