News And Speeches

Today, MI5 will be joining people around the UK to remember those who lost their lives whilst protecting our country. We will be joining the national two-minute silence and reflecting on the sacrifice of those men and women who were killed, or whose lives were changed irrevocably by war. 

We have historically held a Remembrance Day service in Thames House, our headquarters, and whilst that will not be possible this year, we will be holding a short virtual event for our staff and have established a virtual ‘Wall of Remembrance’, for colleagues to pay their personal tributes.

MI5 was active during both the First and Second World Wars, playing a key role in combating espionage, intercepting communications and feeding back disinformation. This included double-cross operations in advance of the D-Day landings, which convinced the enemy that the landings would take place at Calais rather than Normandy. You can find out more about our work in support of the Allied effort in both World Wars here.
