Sir John's move came after an appeal by Assistant Commissioner David Veness to a meeting of more than 100 officers today failed to resolve the dispute. Later, rank and file officers in the elite SO19 were locked in a series of meetings in an attempt to agree their next move. Asked to confirm reports that a quarter of the SO19 officers were refusing to carry arms, Sir John added: "As far as the figures are concerned, I can't give you the exact number but it's escalating."
