London - The Barclays boss is the City's latest fallen idol being cattle-prodded into a Leveson-style public inquiry about endemic rot under his watch.
Tonight he's adamant there's no resigning issue in his running of a huge, corrupt, casino-style bank that regulators have just fined nearly three hundred million squid.
Now the prospect looms of a public hearing conducted under oaf - er...oath! - definitely anathema in this bigwig fantasy world where a banker's word is as close to Gospel as it gets.
However there's plenty of support for Diamond to plead the Fifth according to movers and shakers on the board of a major Illuminati slush fund.
Officials at the Atlantic Council, a US/UK political stink tank, are backing Diamond-Geezer all the way 'as long as he stays schtum about the usual tricky stuff'.
"A sphynx-like aura never harmed Kissinger," is how one anonymous former US Senator put it to QM NewsCorpse reporters.
"Smart money's on Diamond moving to run the European Central Bank."
