M&S has been blasted by Scots for putting a Union Jack on a product containing haggis, neeps and tatties.

A picture of the "British haggis, neeps and tatties en croute" dish was uploaded to Twitter by independence supporter Graham Bell who told his followers to retweet if they found it offensive. At the time of writing, the post has 809 retweets.

The product was released in January as part of the supermarket's Burns Night range.

Ruth Watson, who runs the Keep Scotland the Brand campaign, described the product as "odd and disappointing".

She added: "It is remarkable that Marks and Spencer would fail to make the most of the provenance of a dish so closely associated with Scotland.

"Research repeatedly shows clear provenance is good for business both at home and overseas. It is both odd and disappointing that, yet again, Marks and Spencer fails to #keepScotlandtheBrand."

Many Scots said they wouldn't be shopping in M&S over the issue.

Others suggested the product should have both Saltire and a French flag.

The backlash comes on Scottish Food and Drink Fortnight which runs until September 20 and aims to celebrate the best produce the country has to offer.
