Just exactly how hot is it on the new Boris buses?

We've recorded the temperature onboard a 38 bus between Grays Inn Road/Holborn and Essex Road, Islington this afternoon. Our Political Correspondent Simon Harris's tweets accompany each image.

On Friday, the Mayor Boris Johnson promised to fix the problem, and Transport for London claimed an 'army of engineers' would work throughout the weekend to get the air conditioning working.
