On 4th August 2014 it will be 100 years since war was declared, pitching the nation into one of its hardest and darkest chapters.
Ministers are due to announce how the centenary will be marked over including a candlelit vigil at Westminster Abbey finishing, with the last candle being extinguished at 11pm - the moment war was declared.
It is understood the Government is in talks with various churches, faiths and other organisations to see if the vigil could be replicated around the country.
The idea to commemorate the start of the war with the vigil came from a remark attributed to former foreign secretary Viscount Edward Grey.
He is supposed to have said on the eve of the Great War: "The lamps are going out all over Europe, we shall not see them lit again in our time."
