VIDEO: London Mayor Boris Johnson trips child during friendly football match

London Mayor Boris Johnson needs to stay in the Palace of Westminster and avoid the football pitch as much as possible.

Johnson, who has made at least one horrendous (and hilarious) tackle in a friendly match, struck again this week - this time felling a child.

Why Johnson was on the pitch while the youngsters were enjoying a friendly kickabout is unclear, but his reflexes are going to need some work if he plans on making this a regular occurrence.

Deserving of a yellow card, at least.
