Politicians including Mayor Boris Johnson aren't doing enough to cleanse the air, Kelly said. Beijing last year and Athens in 2004 struggled with air pollution during the games

Err, British politicians don't do things, they make speeches saying they will be done and then move on. Actually getting things done is just so proletarian. After all, their peer group isn't impressed by such things, only by the quality of the speech and the quality of the sponsors who support you.

and if they were worried about air quality why didn't they demand it be fixed BEFORE they gave it to a shithole like london ?
