Sadiq Khan has been lambasted by the London Assembly after he failed to attend a Plenary meeting on his transport strategy.

Instead, Mr Khan sent the Deputy Mayor for Transport, Val Shawcross CBE in his place.

The Assembly has chastised him after all five parties unanimously agreed on a motion to request the Mayor attend all Assembly meetings to which he is invited.

Gareth Bacon AM, who proposed the motion, said his failure to show up showed “a worrying level of contempt”.

“Sadiq Khan needs to realise it is not optional to answer questions about the decisions he has taken and the frustration among members of all parties has been growing.

“We took this unusual step today to send a very strong message to the Mayor.

“I hope he has listened and will be present at future meetings at City Hall.”

Both Ken Livingstone and Boris Johnson attended every single Transport Plenary to which they were invited.
