He added that the ruling came at a time during Brexit negotiations when the world was regularly hearing how Britain’s farming industry had impeccable animal welfare regulations.The Telegraph can reveal that the Go Vegan World group is actually a spin off from an Irish animal rights group founded by a woman who was inspired to go vegan after she adopted two lambs. Sandra Higgins, from Slane in County Meath, set it up last year, after starting a “farm sanctuary” with 100 animals – or “residents” and “non-humans”, as she calls them – in 2008.Initially, she campaigned in her home country of Ireland, but after receiving donations she has expanded her advertising campaign to other countires. Last year her organisation, a not profit company, focused on the UK launching high profile and costly campaigns in Birmingham, Wolverhampton and Newcastle Upon Tyne.The group is particularly keen on targeting university campuses, bus shelters, digital billboards and taxis with their highly emotive adverts.Writing on her website, Ms Higgins, who is in her 50s and obtained a degree in psychology from the Open University, says the pressure group’s goal is “the liberation of non-humans from human suppression and to support them in whatever way possible to regain their sovereignty.”She adds that she also aims to “let the animals be the spokespersons for their rights by their strong public presence”.The group’s YouTube channel features videos including “You Haven’t Lived Until You’ve Hugged a Turkey”.Ms Higgins dedicated Go Vegan World group to the memory of Matilda, a hen that she says she rescued from a “petting farm” in 2012 and died a few years later.Other adverts in her campaigns have featured a picture of a lamb with the words “She has one precious life” or a mouse with the headline “They trust us. We betray them.”But Mr Oakes urged consumers to support farmers at this pivotal time.“Animal welfare standards in the UK’s dairy industry are the highest possible,” he said. “I am a dairy farmer and what I do all day is look after animals who in turn look after me. Their wellbeing is my priority.”The advert at the centre of the controversy explained how someone became a vegan after visiting a dairy farm. Text says calve’s mothers, “still bloody from birth”, search “frantically for their babies”.Meanwhile, the calves “fresh” from their mothers’ wombs “trembled and cried piteously, drinking milk from rubber teats on the wall instead of their mothers’ nurturing bodies.“The ASA said that while it understood concerns that the “emotional and hard-hitting” campaign implied some dairy farms did not comply with welfare standards, it did not mislead people.Instead, it said consumers would recognise many of the comments as the pressure group’s opinions.Ms Higgins welcomed the ASA ruling as a victory for human rights, adding that “dairy is inherently inhumane”. After the publication of the advert, which also appeared in the Sunday Telegraph, the ASA received seven complaints, many from those working in the dairy industry, insisting that the advert was inaccurate and misleading.But on Wednesday, the ASA rejected the complaints claiming people would realise the comments were the pressure group’s own opinions. But Michael Oakes, the NFU’s national dairy board chairman, said he was “angry” and “disappointed” with the ruling and felt sorely let down by the ASA. A controversial animal rights advertising campaign that claims drinking milk is inhumane has been given the thumbs up by the Advertising Standards Agency (ASA).The move has been met with outrage by farmers who claim the advert wrongly suggests that dairy farmers have scant regard for animal welfare.The campaign, which features a picture of a cow behind barbed wire with the headline “Humane milk is a myth – don’t buy it”, was launched in February by Go Vegan World, an organisation set up in memory of a dead hen.
