The controversial introduction of an ombudsman to oversee relations with suppliers will further add to the estimated cost, with shoppers having to pay for the increased bureaucracy, it said.

'The Competition Commission’s proposals will regrettably have serious ramifications for consumers and the UK economy,' Tesco wrote in its final submission to the Commission. Proposals by the regulator to increase red tape in the planning system would mean higher prices for shoppers in the short term, Tesco warned.

'In the longer term the Commission risks freezing investment, limiting expansion and having a detrimental effect, not just on the grocery sector as a whole, but in the wider economy beyond its remit.'

The warning comes as Tesco prepares to announce full-year results on Tuesday.
