Tamás Sulyok signed a constitutional amendment on Saturday, July 18, 2026, immediately terminating his presidency after Hungary's parliament voted to remove him from office.

The Tisza party, which holds power under Prime Minister Péter Magyar, passed the amendment citing a serious loss of public confidence in Sulyok as justification. The measure took effect the moment Sulyok signed it, according to The Guardian. BBC News reported that Sulyok had a deadline of Saturday night, July 18, 2026, to agree to leave.

Sulyok was elected to the presidency in early 2024 by lawmakers from Viktor Orbán's Fidesz party, a nationalist party whose members had regarded Sulyok as a loyalist. Orbán is a former prime minister of Hungary.
