"So @AIannucci OBE joins the Establishment he claims to deride," tweeted Campbell this morning (June 16). "Malcolm Tucker [from Iannucci's The Thick of It] and I do not approve of honours system."
"@campbellclaret It's probably more Establishment to order your army to march into other countries for no reason," the Alan Partridge writer replied, referring to Campbell's involvement in the Iraq war. "Swings and roundabouts."
Campbell went on to claim that he had turned down offers of a peerage twice, and told the political satirist that "three little letters can have more impact than you realise".
After responding to a suggestion that he had previously criticised The Thick of It, Campbell continued to push Iannucci to explain his acceptance of the honour.
"This what I like about twitter," he added. "As u keep going, people move to the argument. WMD good retort to OBE. But @aiannucci still hasn't answered Y."
The Scottish writer declined to comment, and instead signalled he was leaving the conversation.
"I'm off for breakfast." He tweeted. "Anybody coming?"
