The Royal British Legion produced a video this week as part of its Lights Out campaign to mark the First World War centenary.

Everyone in the UK was invited to turn off their lights between 10pm and 11pm on August 4 2014, leaving only a single light or candle on as a “symbolic action of reflection and hope”.

The relatively short video shows a number of celebrities, including Jeremy Paxman and Twiggy, children and military personnel lighting and blowing out a single candle.

It opens with the famous line spoken by foreign secretary Sir Edward Grey on the eve of Britain officially entering the First World War.

“The lamps are going out all over Europe; we shall not see them lit again in our lifetime.”

The candles were lit across the UK to remember the more than one million service men and women who gave their lives in “the war to end all wars”.

Lights Out was a headline project of the cultural programme 14-18 NOW and was initiated by the Department for Culture, Media and Sport.
