Here's good example of working the system - from the retail gazette:
In his letter to Asda, Mr Jones said: “The committee has concerns that the complex company structure within which Asda sits, and associated decisions on financing, may restrict your ability to help meet cost-of-living pressures on your customers.”
In response, the Asda co-owner said it was not uncommon for a business of its size to have such a complex structure.
Issa said the business was set up this way to enable smooth lending practices and fuel future takeover activity.
MPs also asked for more detail about interest-free loans allegedly provided to fund the purchase of private jets.
Issa said EG Group, the petrol forecourt empire owned by the two brothers, had publicly disclosed the loans in its accounts: “The board of directors of the EG Group are aware of, and approved, this arrangement.”
