What we need to do now is go further... to imagine, and then create, a world without war. With the hideous death-toll in Gaza, the chaos in Syria and Ukraine, the turmoil in Libya, that might seem a long way from the reality of 2014. But the important first step is to say "this is possible", and then to start to plan the actions needed to bring a peaceful world into being.
Tonight, as we remember the point 100 years ago when the British Empire formally entered the First World War, the lamps will go out once again. Across the country millions of people will turn off the lights in their homes, businesses and public buildings, taking a moment to reflect on the dire events that were unfolding a century ago.
With World War I and its horrors so much in the public mind I wanted to share the impact that this war to end all wars had on the day-to-day life of women and children in this country through the most normal of items - a knitted sock. The formidable Queen Mary led the movement to keep our troops warm during winter in the trenches, when Lord Kitchener asked her to undertake the huge task of providing 30,000 pairs of socks for our brave lads.
