The Queen has returned to shaking hands despite coronavirus fears.
Earlier this week she did not shake hands, her traditional greeting, with the Sri Lankan High Commissioner Saroja Sirisena and her husband, Dr Sudath Talpahewa.
But she was back to handshaking - without gloves - on Wednesday in a meeting with Professor Mark Compton, Lord Prior of the Order of St John.
She had previously been wearing long gloves to hand out honours gloves amid coronavirus fears.
It came as Prince Charles opted for a more cautious approach at the Prince's Trust awards on Wednesday.
He greeted TV presenters Ant and Dec and Rolling Stones guitarist Ronnie Wood with a 'namaste' gesture.
There is no official guidance on shaking hands in the UK, although well-known medical commentator and GP Dr Rosemary Leonard told the BBC that "we probably ought to stop shaking hands".
Speaking to the awards audience at the awards, Charles said: "Due to circumstances beyond our control we are not joined by as many of those who make such an immense difference to my trust internationally, as we originally planned.
"However, I just wanted to thank them for all their continued support and dedication to my trust."
He also used the traditional Indian greeting at the Commonwealth Day service at Westminster Abbey on Monday, where handshakes were reportedly banned.
During his speech, Charles aimed a quip at his co-hosts over their ongoing success at the National Television Awards.
He said: "They recently won their 19th National Television Award for best presenter.
"So perhaps it is a little bit refreshing for them to be handing out awards rather than receiving them for a change."
Prime Minister Boris Johnson, who was also at the service, addressed the issue of handshaking with reporters afterwards.
He said: "There is a good reason for not shaking hands, which is that the behavioural psychologists say that if you don't shake somebody's hand that sends an important message to them about the importance of washing your hands."
"So there is a subliminal cue there to everybody to wash your hands."
The World Health Organisation declared coronavirus a pandemic on Wednesday. More than 400 Brits have caught the virus and ten have died.
