LFC as a club has paid only £4.1m of interest over the last 2 reported periods. Neither has there been any cash loaned from the club to the holding companies in the last 2 reported periods.
As such the club has not paid any of the interest in relation to the purchase debt, nor has it's cash been paid to pay down the bank debt. All that was done by loans from Kop Football (Caymen) Limited.
As for interest due on loans from the owners, this is unlikely to be paid whilst there is bank debt outstanding, it'll be part of the covenants placed on that money as it is the case that the loans cannot be demanded for repayment if it makes the companies insolvent.
And if you don't believe me then just read the accounts.
