New evidence suggests the Bank of England may have been involved in the Libor rigging scandal.
A secret recording from 2008 uncovered by the BBC suggests that the UK's central bank pressured commercial banks to push Libor rates down during the Financial Crisis.
Libor is the rate at which banks lend to each other, setting a benchmark for mortgages and loans for ordinary customers.
In one section of the recording, Senior Barclays manager Mark Dearlove speaks to Libor submitter Peter Johnson, telling him: "The bottom line is you're going to absolutely hate this... but we've had some very serious pressure from the UK government and the Bank of England about pushing our Libors lower."
