Gordon Brown held a Cabinet meeting at Durham Johnston School, on the outskirts of the cathedral city. He was shown round the new #163;24 million premises by pupils who gave up part of their half-term holiday.
Officially opening the school, the Prime Minister said: "It is the first time the Cabinet has ever met in a school or the North East. I hope you see we behave ourselves."
Security was tight, with a strong police presence and visitors sent through airport-style scanners and frisked.
Mr Brown was escorted round by head Carolyn Roberts and local Labour MP Roberta Blackman-Woods. DM.
