The Guardian article reveals that the email concerned afforts by Labour Chief Fundraiser, Lord Levy, to 'shape' the evidence which Ruth Turner would give to the Police. Another document (whose existence, so far as I am aware, has never been revealed before) is an account of a meeting between Ms Turner and Lord Levy which Ms Turner has given to her lawyers and been passed to the Police. Police efforts have in recent months apparently concentrated in trying to piece together the evidence provided by this legal document and by the email sent to Jonathan Powell. The Guardian apparently has no information concerning in what way the evidence to be given by Ruth Turner was to be modified, nor whether such changes were to be 'significant'. The Guardian article also casts doubt on the existence of the infamous email which the BBC alleges was sent.
My interim conclusion, at this stage of the proceedings, has to be along the lines of:
When first we practice to deceive!
(Sir Walter Scott to the rescue)
(*) But it wouldn't have prevented a possible future prosecution of the Guardian and its Editor for potentially jeopardising the case against certain of the Labour Party's leading lights and lesser minions. I am forced to point out that the Guardian is, traditionally, a left-leaning newspaper, although I would accept it has probably in this instance been motivated more by journalistic enthusiasm than by a desire to contaminate evidence, but this enthusiasm may nevertheless have affected its judgement about what was the right thing to do in this case.
