I am grateful for that intervention as I did not know that. I am sure that the House will be extremely grateful for that contribution and I suspect that many of us will have learned something from it.
In that same spirit, I wish to reflect briefly for a moment on the significance of people such as Walter Tull, the first black officer in the British Army; that was just one small step on the road to affording ethnic minorities the recognition and respect they deserve.
We should also take the opportunity to reflect on the fact that the war left its mark on this place where we gather today. Of all the countries that went to war in 1914, Britain’s was the only Parliament to debate entry into the conflict. When the lamps went out that night on 4 August, it left more than just a shadow over this place; 251 existing and future MPs would serve in the first world war, and 19 from the Parliament of 1914 would not come back. Their shields mark this Chamber and watch over us today, and they were joined by 24 Members of the other place, as well as 20 parliamentary staff—clerks, waiters and cleaners—who were also killed in action.
