Water cannon ban decision 'wrong', says Boris Johnson

London Mayor Boris Johnson has said a decision by the home secretary not to allow police to use water cannon in England and Wales is "wrong".

Theresa May said the decision on whether to authorise water cannon was a "serious" one, and a lengthy study had been carried out to assess their safety and effectiveness.

Mr Johnson authorised the £218,000 purchase of three second-hand cannon from the German police.
