Royal children George, Charlotte and Louis joined the nation in saluting NHS workers battling the coronavirus pandemic.
In a gesture of thanks to frontline staff, people across the UK joined a mass round of applause from their doorsteps, windows and balconies at 8pm on Thursday.
The Duke and Duchess of Cambridge, William and Kate, posted a video of their three children clapping, while Prime Minister Boris Johnson and Chancellor Rishi Sunak also joined in from Downing Street.
There was also clapping at Windsor Castle, while Prince Charles and the Duchess of Cornwall were said to have joined in from the Balmoral estate.
The Duke and Duchess of Sussex posted a message on their Instagram story, writing: “Thank you for all that you continue to do! Applauding you from across the pond.”
Many across the UK joined in, with some holding signs, cheering and letting off fireworks.
Labour leader Jeremy Corbyn also took part, appearing to cheer in a video.
One supporter played Tina Turner’s (Simply) The Best to their street as others clapped along.
Emergency services, including police officers and firemen, also showed their support.
In a post on Twitter, the stars of James Bond – including 007 himself – filmed themselves clapping.
The organisers of the Clap for Carers campaign, which was started online, say it was staged because “during these unprecedented times, [NHS staff] need to know we are grateful”.
A number of landmarks, including the Wembley Arch, Royal Albert Hall, Lincoln Cathedral and the Principality Stadium, were lit up in tribute.
Health Secretary Matt Hancock said in a video message for LBC: “My colleagues in the NHS do so much to look after us, especially in our hour of need and never more so than during the coronavirus crisis, so let’s join together at 8pm tonight to say thank you to everyone in the NHS.”
The tribute is part of the #lightitblue campaign, which has been organised as a way to say thank you to hardworking healthcare staff.
