Barclays scandal: Paul Tucker asks to give evidence to MPs Lord Myners, who was City minister in the last Labour government, has said he is confident that no one at the Treasury at the time ordered Barclays to begin rigging its interest rates. There have been suggestions that Baroness Vadera, one of Mr Brown's closest advisers, was the senior figure referred to in the Barclays note of the discussion between Mr Diamond and Mr Tucker. She told the BBC World at One: "I didn't speak to Paul Tucker or anyone at the BoE about Libor." Shadow Chancellor Ed Balls said "at no point did I have any conversation with Paul Tucker" about Libor. "I had no conversation with anybody about the Libor market during any of those periods and at no point, in any of the time that I was a minister or an adviser, were concerns raised about the Libor market from the FSA, the Bank or the Treasury to me," he told BBC News. The idea that I have an issue on this or that I should be nervous this afternoon is completely false and untrue ... and I would be very happy to say that to an inquiry. Earlier today, Nick Leeson, the rogue trader who brought down Baring bank, warned of the danger of today's grilling by MPs of Mr Diamond. "Today's proceeding ... could potentially be very damaging for the country, if the complicity that is kind of being alleged at the moment with the FSA and the Bank of England is proven," he said.
