London Mayor Sir Sadiq Khan has delayed implementing a ban on betting adverts on the Tube network until a formal definition of harmful gambling is agreed upon. Khan’s 2021 re-election manifesto promised to rid the Underground of such promotions, but he now wants more detail from the government before taking action. The delay has been criticized by opponents who argue that Londoners are already being exposed to gambling adverts while travelling on the transport network.

Mayor Sir Sadiq Khan has been accused of “stonewalling” questions about whether London has a problem with so-called “grooming gangs”.

His Tory rival Susan Hall made nine successive attempts at Mayor’s Question Time to ask Sir Sadiq whether there were gangs operating, or previously active, in the capital.

But Sir Sadiq repeatedly asked Ms Hall, the former Tory mayoral candidate, to clarify what she meant by grooming gangs, claiming: “I’m not clear what she means.”

The result of the London mayoral election formally declares Sadiq Khan’s victory for a third term as Mayor of London.

London has become the world’s largest pollution charging area after the ultra-low emission zone (Ulez) was expanded to include the whole of the capital.
