Mayor of London: Sadiq Khan sworn in for historic third term

Sadiq Khan has been sworn in for his historic third term as mayor of London after he was re-elected at the weekend.

He said he would help improve the lives of young Londoners, from birth to buying a house and getting a job.

Mr Khan also said he would make the Thames safe to swim in, increase the number of police officers and have a zero-emission bus fleet by 2030.

He signed the declaration during a ceremony at London's Tate Modern on the South Bank in central London.
