The Royal British Legion has brought together celebrities and veterans to ask the British public to take part in LIGHTS OUT, a national initiative to commemorate the centenary of the First World War.
Famous faces including Jeremy Paxman, Twiggy, David Gandy and Louis Smith feature alongside Chelsea Pensioners and service personnel in a video to promote the initiative which will complement a candlelight vigil taking place on the evening of Monday at Westminster Abbey.
Communities across the UK are being invited to take part in this national moment by switching off their lights 10pm-11pm on August 4, the date Britain entered the war 100 years ago, and illuminating their homes with a single candle or light. Members of The Royal British Legion have already planned 130 events nationwide for the public to participate in, with more to be announced.
LIGHTS OUT takes inspiration from the famous words of wartime Foreign Secretary Sir Edward Grey, who remarked on August 3 1914: "The lamps are going out all over Europe; we shall not see them lit again in our lifetime."
Charles Byrne, Director of Fund-raising at The Royal British Legion, said: "Sir Edward Grey's stirring words are the campaign's foundation.
"Our vision is that over one million candles will be lit across the UK, commemorating every serviceman and woman who died during WW1.
"We hope to see candles lit at every war memorial, community centre and home in every village and in every community."
To support LIGHTS OUT and as part of a special partnership with Marks & Spencer, limited edition centenary candles are available to purchase in stores and online.
Profits will be donated to the legion to support the charity's vital work with the current and ex-members of the Armed Forces, and their families.
