Hungary’s new prime minister has pledged to revive the country’s economy following the first change of government in 16 years in the Central European nation.

Peter Magyar was sworn in at the National Assembly in Budapest on Saturday.

His party Tisza won more than two-thirds of the seats in the parliamentary election in April, ousting longtime Prime Minister Viktor Orban.

Magyar said in an address to lawmakers that the Hungarian people have given him and his party a mandate to open a new chapter in the country’s history.

He stressed his intention of rebuilding the economy whose growth has remained sluggish.

About 80,000 people gathered in front of the National Assembly for a ceremony to celebrate his swearing-in.

The prime minister expressed gratitude for their support in the election.

A university student said he had been waiting for this moment. He also said Magyar has a great responsibility, and supporters believe in him.

During Orban’s 16 years as leader, the European Union suspended funding to Hungary, citing corruption and a lack of judicial independence.

Magyar is believed to try to mend ties with the EU and request the resignation of the country’s president who was appointed by the Orban government.
