Hungarian Prime Minister Viktor Orbán has declared that his government will be holding a referendum on a controversial anti-LGBT law.Orban made the announcement in a live video on his official Facebook page.The law, officially called the Children Protection Act, has the stated purpose of safeguarding children's well-being and fighting paedophilia.But it has been widely criticised for being discriminatory against members of the LGBT community and the European Union has launched legal action against Hungary over the law.The law was initially passed during Pride Month, in June, by the Hungarian government and outlawed depictions of homosexuality and transgender issues in both the school curriculum and on TV shows that are aimed at minors.
