The first Blue Plaque commemorating a secret agent is to be unveiled today.
Wing Commander F.F.E. Yeo-Thomas, better known by his codename, White Rabbit, was the most highly-decorated secret agent of the Second World War.
The plaque will be unveiled by his niece Carol Green at his home in Camden. Historian Mark Seaman, author of Bravest of the Brave, reflects on the secret agent's life.
