Firms from Ikea to a Michelin star restaurant have signed up for a campaign in defence of same-sex parenthood in Hungary, bringing unexpected resistance to Prime Minister Viktor Orban’s anti-LGBTQ crackdown. The Family Is Family campaign has enlisted 140 companies so far, up from 40 in February, in response to steps by Mr Orban to effectively ban adoption for same-sex partners and enshrine in the constitution the idea that marriage is possible only between a man and a woman. The ranks include international giants such as Levi Strauss & Co and Warner Media’s HBO, as well as small- to mid-sized local businesses. The drive’s popularity is surprising even its organisers in a country where companies have long been wary of taking a stand against Mr Orban. Hungary’s premier since 2010, Mr Orban has sought to consolidate his hold over courts and civil society, and is embroiled in clashes with European Union leaders alarmed by his authoritarian turn.
