Founded in 2010, Save Me’s first campaign opposing badger culling attracted more than 300,000 signatures - then the biggest petition to ever grace the government’s website.
Most recently, the charity launched BACVI, the Badger and Cattle Vaccination Initiative, which encourages farmers and conservationists to unite to combat bovine tuberculosis.
The scheme champions targeted vaccination of both badgers and cattle following what Save Me described as two "deeply-flawed and incredibly disastrous" pilot culls.
In a 2010 interview Brian famously said he would rather be remembered for his animal rights work than for his music or scientific work.
He is a staunch supporter of several animal charities, including the RSPCA, the International Fund For Animal Welfare, the League Against Cruel Sports, PETA UK and the Harper Asprey Wildlife Rescue.
In May 2013, the 67-year-old teamed up with actor Brian Blessed and Flash cartoonist Jonti ‘Weebl’ Picking, as well as animal rights groups, to form "Team Badger" - a coalition of organisations whose aim is to fight badger culling. He recorded a charity single with them called Save The Badger Badger Badger, which reached number one on the iTunes rock chart.
