George Psaradakis, the driver of the No. 30 bus which exploded in Tavistock Square during the 7/7 attacks, helped present a Labour campaign event today.

The driver introduced Tessa Jowell, Labour’s London minister, and Alistair Darling, who attacked the Tory perception of London as a ‘broken society’.

“Not one person I’ve met has told me that London is broken and asked me how we’re going to fix it,” Ms Jowell said.

“By characterising London as broken, the Tories simply demonstrate that they do not understand our city and the communities whose votes they are asking for.”

Alistair Darling said: “The choice this week couldn’t matter more. I can tell you from personal experience – when faced with the scale of challenges we’ve seen in the last few years, every judgement is crucial.

“As we’ve seen in other countries, we are not out of the woods yet.”

The event took place at Centrepoint, where Gordon Brown pledged full-scale parliamentary reform earlier in the campaign.
