During 2008 I worked closely with a financial institution that was working with departments of the then Prime Minister, Gordon Brown, and his trusted sidekick, Shriti Vadera (now Dame Vadera). In casual conversation, I learned from various managers who had been close to that advice, that these two senior figures in the UK government had been making direct calls to senior figures at UK banks 'requesting' that they keep LIBOR down.
In light of the latest news, I find it entirely credible that the government and the Bank of England conspired to demand that UK banks provide lower LIBOR quotes in the "cause of the greater good".
"This puts the question of how the authorities viewed the supposedly illegal manipulation of LIBOR in a completely different light"
Question of Proof
Just because people are discussing things is not proof those things happened.
