The UK's 4^th largest supermarket is calling for the Chancellor to make changes to tax rules to prevent foreign rivals gaining an unfair competitive advantage.

Morrisons' Finance Director Richard Pennycook has told Jeff Randall Live that it's time companies came clean on tax and that tax attached to economic activity in the UK should stay here.

"We want a level playing field. What applies to one company should apply to another. There are big differentials in what companies are paying."

Last year Morrisons paid UK corporation tax of £281 million, that's over a quarter of its profits. It has a UK market share of around 12%.

In contrast its rival, German owned budget chain Aldi has confirmed to Sky News it paid £12.7 million in UK corporation tax last year on a profit of £70.5 million. It has a market share in the UK of around 3%.

Mr Pennycook says, "The Chancellor must look into this and regulate. Taxes on activity here in the UK should stay here. Transparency is very important."

Aldi has released this statement. "Aldi has always respected and complied with the tax laws. Since 1990 we have invested significantly in establishing our business, in line with UK tax legislation these early trading losses have reduced our taxable profits and tax liabilities."

Discount supermarket chain Lidl which has 580 UK stores is also German but privately owned. It didn't disclose to Sky News how much corporation tax it paid in the UK last year.It issued this statement. "Lidl do not engage in any tax avoidance schemes nor do we have any subsidiaries in "low tax" countries. At Lidl, we believe that every company operating in the UK has a social and economic responsibility to pay corporation tax. As a private company, we are under no obligation to release any financial statistics."
