Excerpts:
"But Sir Bernard Ingham, former press secretary to Baroness Thatcher, said Mr Campbell had symbolised an "appalling era of government communication" and spin.
He blamed this on the prime minister, rather than on Mr Campbell himself, however.
"It points the finger at Tony Blair because he [Campbell] worked under Blair's regime," he said.
"Blair is responsible ultimately for the loss of trust because he allowed the methods Campbell employed to operate."
And
Political commentator Michael Brown likened the departure of Mr Campbell to Mr Blair having his brain taken out.
The former Tory MP told Sky News: "Of course he will be greatly missed by Tony Blair.
"It's like having Tony Blair's brain literally taken out and how he's going to be able to continue without Alastair Campbell is going to be very interesting to watch.
"Alastair Campbell has been taking vital political decisions, offering vital political advice to the prime minister."
Campbell sounds like Blair's Karl Rove. This may indeed be the beginning of the end for Blair as well.
