The story was based on a Freedom of Information request from the paper and followed up by the Telegraph and the Mail.
The Sun's 'exclusive' by Tom Wells began:
Whitehall chiefs paid a PR firm £45,000 to teach gypsies about an EU rule asking people to promise not to EAT their horses.
However, while the Sun and Mail articles are still live, the Telegraph's has been deleted. Why?
Well, it might have something to do with this statement put out by the 'Whitehall chiefs' at the Department of Environment, Food and Rural Affairs:
Myth bust: Marketing campaign on Horse Identification rules
The myth: The Sun and Daily Telegraph have suggested that Defra funded a marketing campaign to ask travellers not to eat their own horses.
The truth: It was nothing to do with eating horses. The campaign explained changes to EU rules which meant owners needed to have their foals and any previously unidentified horses micro-chipped when they applied for horse passports. This was to improve disease control and help prevent the export of contaminated meat. No part of the campaign involved asking the owners to promise not to eat horse meat.
