Ex-director of public prosecutions Lord Macdonald, who criticised the Metropolitan Police's handling of the plebgate investigations, has warned a missile is heading "straight for the heart of the Metropolitan Police" if it turns out the use of the word "pleb" was fabricated.
Writing in The Times, he added:
It seems quite outrageous that, in the face of the simplicity of the allegations and this significant commitment of public resources, the investigation rambles on with no apparent end in sight.
We are talking here about the resignation of a British Cabinet minister, a resignation forced upon him at the height of his career by police allegations that are now seriously called into question.
An expeditious and thorough investigation should have been perfectly possible.
