Plans to get the Met Police water cannon by this summer are moving ahead as planned. Boris Johnson says he will ask Londoners their views on use of the machines "in the most extreme circumstances".
A final decision by London policing authorities over whether to proceed is expected in February. It would then be up the Home Secretary to decide whether to licence use of water cannon which it is hoped will be available for police in London by the summer.
