The Financial Conduct Authority has said it has "no current plans" to launch another probe into Barclays' role in the LIBOR-rigging scandal. It comes after allegations that documents provided in a court case yesterday showed the part the Bank played in the debacle went "further and wider than the regulatory findings."The comments were made by lawyers acting for Guardian Care Homes (GCH), which is suing Barclays over interest-rate swaps. GCH alleges that Barclays mis-sold it inappropriate interest rate hedging products based on LIBOR that ended up costing it millions of pounds as rates fell.Barclays denies mis-selling and says the LIBOR-rigging allegations are irrelevant to the dispute. The bank is asking the Court of Appeal to overturn an earlier ruling that GCH could amend its claim to include LIBOR-related allegations."Barclays continues to bury its head in the sand despite overwhelming evidence that the bank was manipulating LIBOR in order to profit from swaps," said Guardian Care Homes CEO Gary Hartland. "My swaps have cost me £12m so the suggestion that these allegations are irrelevant is fanciful."Barclays has already been fined $453m by US and British authorities last year over attempted manipulation of LIBOR rates. Transcripts of conversation between executives, which were provided by GCH for the court case and emerged yesterday, indicated that certain Barclays' executives knew the bank had submitted lower-than-accurate LIBOR rates. Other evidence implied a former Barclays' employee Quan Hui Lee had asked colleagues to enter lower rates.Quan Hui Lee e-mailed colleagues in London instructing them to "go get LIBOR down", according to e-mail evidence.Ian Pike, a Barclays employee in London who submitted rates, was cited as having written back: "I'll do my best boss!" "The documents ... show that Barclays' misconduct goes further and wider than the regulatory findings," GCH's lawyers said.But a spokesman for the FCA told Reuters: "There are no current plans to launch a new investigation," The case against Barclays is seen as a test case that could in theory open the floodgates to similar claims by other companies that took out deals linked to LIBOR rates with other banks.Shares in Barclays were down 1.11% at 272.2p at 13:53 on Friday.TB
