The debt is the amount that Venkys London Ltd " owe " the Parent Company based in India, due to their " investment " or purchase of Shares.... hence the debt showing as " Called up Share Capital " .... this in addition to any Bank debt, Loans, etc in the Accounts...
Like Bolton's debt funded by Eddie Davis, and Wigan's funded by Dave Whelan, it isn't a big problem if the Venkys don't want it back and and are prepared to invest more. Once the funding tap is turned off, as Davis did, then problems mount up very quickly....
