London Mayor Sadiq Khan has joined calls for a review of the 10pm curfew, accusing the move of doing “more harm than good.” In an update to the London Assembly this week, Khan said that in his view, the curfew not only appears to be ineffective but could be counterproductive in curbing infection rates.The number of new cases in the capital rose by 394 on Wednesday (07 October) to 1,310, the third highest daily regional rise in the UK.
