People in the UK are being encouraged to show their appreciation for the country's nurses and doctors fighting the coronavirus pandemic by taking part in a huge round of applause.
At 8pm tonight, people at home are encouraged to clap from doors, windows, gardens and balconies to set off an applause for NHS staff working on the frontline of the crisis.
Here's everything you need to know about the appeal...
What is Clap for Carers about?
The Clap For Our Carers campaign was launched by yoga teacher Annemarie Plas to thank all doctors, nurses, pharmacists, GPs and NHS staff working hard to help those affected by Covid-19 "during these unprecedented times".
Ms Plas shared a post on Instagram urging people to "clap for carers" and the message was shared thousands of times across social media.
The 36-year-old emphasised the clap was not just for NHS staff, but for pharmacists, dentists, supermarket workers and other essential workers on the frontline.
David and Victoria Beckham and Green Party MP Caroline Lucas are among those who have backed the plans.
Mrs Beckham wrote on Instagram: "Words can't describe how thankful we are for all the bravery and hard work of the healthcare workers during this uncertain time. Let's all join together next week on March 26 to show our gratitude and solidarity with those on the frontline."
Delighted with the success of her campaign, organiser Ms Plas told Sky News: "It made me feel really warm inside that I wasn't the only one that felt like that.
"It's such a simple message and we take so many things for granted, and now all these freedoms and options are taken away from us, we start to realise [what we have]. It's a good time to show how thankful we are."
She added: "To have all these celebrities spread the message to all their followers, I just felt so grateful and thankful."
Hundreds of thousands of people across the UK are expected to take part in the applause tonight, Thursday, March 26, at 8pm.
Those who take part in the nationwide clap have been encouraged to live stream or film the event and upload the footage to social media with the caption #clapforourcarers.
The campaign poster reads: “During these unprecedented times they need to know that we are grateful.
"Please join us on: 26th March at 8pm for a big applause (from front doors, garden, balcony, windows, living rooms, etc) to show all nurses, doctors, GPs and carers our appreciation for their ongoing hard work and fight against the virus.
"Please share this message, so we can make sure the word spreads and reaches all to join!"
Similar events to show appreciation for health workers have already been held in countries including Spain, France and the Netherlands.
