RBS claim it's 'co-operating' on Libor is false, says Canadian regulator "The suggestion that the RBS Group is "co-operating fully" with the Bureau is false," the authority said in a statement posted on its website. It added: "The RBS Group has not applied to the Bureau's Immunity or Leniency Programs and, in fact, has challenged a production order issued by the Ontario Superior Court of Justice in relation to the Bureau's investigation." Phil Norris, a spokesman for the CCB, told reporters: "We take misleading statements regarding our investigations very seriously, so in this case we did not hesitate to release a statement, to take the appropriate action to correct them," The CCB, which is investigating allegations that the key interest rate, the London Interbank Offered Rate (Libor), was rigged, asked five banks to submit documents in May 2011. RBS, which was one of the five, said it could not comply with the request without breaking UK rules of data protection and private banking. The two sides have been fighting a legal battle ever since. This week RBS said:"To overcome this issue we have offered a number of alternative mechanisms, however, thus far, the bureau have refused these offers. We have worked through this problem with other regulators and remain committed to co-operating fully with the CCB. RBS is being investigated by regulators in the UK and America as part of the international probe. In June Barclays became the first bank to settle claims. The bank was fined £290m triggering a fall-out that led to Bob Diamond being ousted.
