People for the Ethical Treatment of Animals (PETA), backed by Sir Roger Moore, have been campaigning to have foie gras removed from the shelves of Fortnum & Mason. A similar campaign persuaded Sefridges to stop stocking it in 2009, but Fortnums is adamant that it will not budge.
So why has this row erupted, and what's wrong with foie gras?
PETA has been targeting Fortnum & Mason with a campaign to persuade them to take foie gras off the shelves. The high-profile involvement of Sir Roger Moore has helped garner publicity for the pressure group, which has issued a video showing footage of animals being force fed, with some highly distressing images.
The product's name literally translates as 'fatty liver'. It is produced by over-feeding ducks or geese, so that their livers swell to many times their normal size. The practice of producing it has been banned in the UK over animal welfare concerns. PETA wants to see its sale banned in the UK too.
It has had some success, and in 2009 persuaded Selfridges to take the product off the shelves. Over the years it has periodically targeted Fortnum & Masons too, but has met robust resistance.
Fortnum & Masons has met the campaign head-on. A spokeswoman pointed out to AOL that: "We will continue to stock foie gras because our customers ask for it. Fortnum & Mason is a stockist of artisan, traditional foods, so we sell a number of products that you may not find elsewhere. People come to us specifically for this sort of thing."
She added that far from being put off by the campaign: "In the last two weeks we have seen demand for it increase 60%."
She said that Fortnums works closely with its suppliers: "We have a gold standard for food production and we work to ensure that production meets these standards." The shop has pointed out that geese reared for their livers for the shop have access to fresh water and good air circulation around the farms. It added that the footage in the video was not taken from the farms producing foie gras for the store.
10 of the biggest consumer rip-offs

Using a mobile phone to make and receive calls, send texts and browse the web while abroad can be extremely costly – especially if you are travelling outside the European Union (EU), where calls can cost up to 10 times as much as at home.
To avoid high charges, Carphone Warehouse suggests tourists ensure a data cap is in place, use applications to check data usage, turn off 'data roaming', avoid data-intensive applications such as Google Maps and YouTube and use wi-fi spots to update social networking sites.
Payment Protection Insurance (PPI) is supposed to help people to continue meeting their loan, mortgage or credit card repayments if they fall ill or lose their jobs. However, policies are often over-priced, riddled with exclusions and sold to people who could not make a claim if they needed to.
At one point, sale of this cover - which was often included automatically in loan repayments - was estimated to boost the banks' profits by up to £5 billion a year.
Now, though, consumers who were mis-sold PPI can fight back by complaining to the bank or lender concerned and taking their case to the Financial Ombudsman Service (08000 234567) should the response prove unsatisfactory.
It could be you, but let's face it, it probably won't be. In fact, buying a ticket for the Lotto only gives you a 1 in 13.9 million chance of winning the jackpot.
With odds like that, you would almost certainly be better off hanging on to your cash and saving it in a high-interest account.
No-frills airlines such as EasyJet may promote rock-bottom prices on their websites. But the overall fare you pay can be surprisingly high once extras such as luggage and credit card payment fees have been added - a process known as drip pricing.
Taking one piece of hold baggage on a return EasyJet flight, for example, adds close to £20 to the cost of your flight, while paying by credit card increases the price by a further £10.
It may therefore be worth comparing the total cost with that of a flight with a standard airline such as British Airways.
Cash advances, which include cash withdrawals, are generally charged at a much higher rate of interest than standard purchases.
While the average credit card interest rate is around 17%, a typical cash withdrawal of £500, for example, is charged at more than 26%.
What's more, as the interest accrues from the date of the transaction, rather than the next payment date, costs will mount up even if you clear your balance in full with your next payment.
Supermarkets such as Tesco and Asda often run promotions under which you can, for example, get three products for the price of two.
However, it is only worth taking advantage of these deals if you will actually use the products. Otherwise, you are simply buying for the sake of it, which is a waste of your hard-earned cash.
Buy a train ticket at the station on the day of travel and the price is likely to give you a shock - especially if you are travelling a long distance at a busy time of day.
However, you can cut the cost of train travel by 50% or more by going online and making the purchase beforehand - especially if you book 12 weeks in advance, which is when the cheapest tickets are on sale.
Other ways to reduce the price you pay include avoiding peak times and taking advantage of so-called carnet tickets, which allow you to buy, for example, 12 journeys for the price of 10.
Most High Street banks offer packaged accounts that come with monthly fees ranging from £6.50 up to as much as £40, with a typical account charging about £15 per month.
Various benefits, such as travel insurance and mobile phone insurance, are offered in return for this fee. But whether or not it is worth paying for them depends on your individual circumstances.
