Sunday Times claims Ed Balls ran Labour's smears unit

From tomorrow's Sunday Times:

Ed Balls, the schools secretary, used Damian McBride, the disgraced spin doctor, to smear ministerial rivals and advance his own ambitions, a Downing Street whistleblower has claimed.
In an explosive new twist to the e-mail affair, a No 10 insider has revealed that Balls was the mastermind behind a “dark arts” operation by McBride to undermine colleagues.
He claims the education secretary is running a destabilising “shadow operation” inside Downing Street to clear his path for the party leadership if Labour loses the next election.
The insider said: “There is now an operation within an operation at No 10 and it answers to Ed Balls.”

Now see what the News of the World has to say.

I am enjoying this.
