This picture came from one of Tony Blair’s last speaking engagements as PM last year. However, it has never seen the light of day until now. I was doing a PR job for an organisation hosting a breakfast meeting where an invited audience was given the opportunity to question the PM on policy.

Afterwards I was asked to go to the green room and photograph a smaller meeting. Blair was clearly a little peckish so everyone stood around while he ate a banana. It was one of those precious unscripted moments and I got a few frames before I was stopped. The man on the right of the picture was actually talking to Patricia Hewitt.

Understandably my employers that day were worried that publication would steal their thunder. A classic example of the compromises we make when we do PR.
