A lawmaker in Belgium last week became Europe’s highest-ranking transgender politician.

The Brussels Times reported Prime Minister Alexander De Croo named Petra De Sutter as one of his government’s seven deputy prime ministers. The newspaper said De Croo also appointed De Sutter, a member of Groen, the Flemish Green Party, as his civil service minister.

King Philippe on Thursday swore in De Croo’s new government.

De Croo and De Sutter are both from Belgium’s Dutch-speaking region. De Sutter is also a former member of the European Parliament.

“I am proud that in Belgium and in most of Europe your gender identity does not define you as a person and is a non-issue,” tweeted De Sutter on Sunday. “I hope that my appointment as minister and deputy prime minister can trigger the debate in countries where this is not yet the case.”

De Sutter ended her tweet with the hashtag “fight transphobia.”
