Boris Johnson knocked over a child during a game of street rugby in Japan.

The mayor of London took out the 10-year-old schoolboy as he raced down the mini turf pitch in Tokyo.

Toki Sekiguchi hit the ground and suffered some pain but was soon up and running again.

He said: 'I felt a little bit of pain but it's OK.' The schoolboy said it had been 'enjoyable' meeting the mayor.
