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 amendment was tabled on Monday and adopted on Tuesday. Opposition politicians, the organisers and NGOs have said this was a deprivation of people's rights, a protest was held just a few hours after the amendment was passed.

Hungary has criminalised organising or participating in Pride parades, and granted authorities facial recognition powers to monitor attendees.
