A new anti-LGBTQ+ law banning Pride events and allowing authorities to use facial recognition software to identify those attending the festivities was passed in Hungary on Tuesday, leading to a large demonstration on the streets of Budapest.

Hungary's president has signed a law proposed by Prime Minister Viktor Orban's ruling party that will ban LGBTQ+ communities from holding their annual Pride march, defying criticism by human rights organisations that it restricts freedom of assembly.

The move by Hungarian lawmakers is part of a crackdown on the country’s LGBT community by the right-wing Viktor Orban government. The law, supported by Mr Orban’s Fidesz party and their minority coalition partner the Christian Democrats, was pushed through parliament in an accelerated procedure after being submitted on Monday.
