A Christian bakery has won its appeal against a ruling that it unfairly discriminated against a gay man by refusing to make a cake bearing a pro-gay marriage slogan.

In a unanimous decision, the UK Supreme Court ruled in favour of the bakery in a landmark ruling on Wednesday.

Belfast High Court ruled in 2015 that husband and wife Daniel and Amy McArthur, who run the bakery, had discriminated against a customer when they refused to bake him a cake with the slogan “Support Gay Marriage” on it. They were ordered to pay £500 in damages.
