Moments after it was announced Theresa May will replace David Cameron as Prime Minister, Mrs May signed a pledge committing to remembering the Holocaust.

In what is thought to be her first act as Prime Minister-in-waiting, Mrs May signed a pledge launched by the Holocaust Educational Trust in memory of Sir Nicholas Winton, at its annual ambassador’s conference.

Sir Nicholas, the British hero who saved hundreds of children from Nazi persecution during the Second World War, was the inspiration behind the initiative encouraging people to stand up to hatred and intolerance.

Ambassadors at the conference held in central London on Monday were encouraged to share their individual pledges to fight prejudice along with the hashtag #ShapeTheFuture on social media.

Mrs May shared her own pledge on Twitter.

The programme involves young people who have been chosen by the trust to run outreach projects using the knowledge they have gained from participating in its Lessons from Auschwitz scheme.
