Prince Andrew served in the military for more than two decades (Picture: PA).
The Duke of York has announced he is stepping back from public duties "for the foreseeable future".
Prince Andrew's decision follows the reaction to his BBC Newsnight interview about his friendship with convicted sex offender Jeffrey Epstein.
It means that while he will continue his patronages, he will not publicly appear in support of them.
The organisations he will stop publicly representing include various military charities.
Buckingham Palace has confirmed that as a royal colonel and military veteran he will continue to attend Remembrance Day and Trooping the Colour events, as well as keeping his military titles.
Last year, the Duke took part in Trooping the Colour for the first time as Colonel of the Grenadier Guards.
Prince Andrew has faced growing criticism following a BBC interview about his friendship with Jeffrey Epstein who took his own life while awaiting trial on sex-trafficking charges.
Epstein had previously been convicted of a separate sex offence.
The Duke, meanwhile, has been accused by American woman, Virginia Roberts, of having sex with her when she was 17 years old - an allegation he insists is untrue.
Five days after the broadcast of the BBC Newsnight interview, the Duke announced he was stepping back from his public role.
In a statement, he said the Queen had given her permission.

He added: "My former association with Jeffrey Epstein has become a major disruption to my family's work and the valuable work going on in the many organisations and charities that I am proud to support.
"I continue to unequivocally regret my ill-judged association with Jeffrey Epstein.
"I deeply sympathise with everyone who has been affected and wants some form of closure."
Prince Andrew has supported more than 30 military charities, including as patron of SSVC, the parent charity of Forces TV and BFBS.
