VALLETTA, Malta (AP) — Maltese voters went to the polls a year early Saturday in a snap election called by Prime Minister Joseph Muscat after allegations his wife owned a company linked to the Panama Papers scandal sparked an official investigation.

Surveys showed Labour’s Muscat was likely to win a second, five-year term. But polls indicated one-fifth of voters were undecided, giving the National Force made up of the Nationalist Party and newly formed Democratic Party a slight chance.

Turnout was 92 percent of the more than 340,000 eligible voters, the electoral commission said.

The Panama Papers scandal, which detailed offshore companies and other financial data of the rich and powerful, exposed Malta’s energy minister and Muscat’s chief of staff as having acquired a company in Panama.

Muscat called new elections and ordered a magisterial inquiry midway through Malta’s first-ever stint at the presidency of the European Council after allegations surfaced in April that his wife also owned a company in Panama. The Muscats deny the allegations.

Setting up an offshore company is not illegal or evidence of illegal conduct, but shell companies can be used to avoid taxes or launder money.

After the publication of the Panama Papers last year, Muscat was criticized for retaining Energy Minister Konrad Mizzi and chief of staff Keith Schembri, whose names figured in the document dump. They acknowledged that they acquired the companies but denied wrongdoing.

Since then, two other magisterial inquiries have been opened after opposition Nationalist leader Simon Busuttil lodged money laundering and kickback allegations against Schembri. Schembri denies any wrongdoing.

None of the investigations had finished before Saturday’s vote, prompting Busuttil to accuse Muscat of taking the country to the polls early to “save his skin.”

During the campaign, Busuttil - Muscat’s prime challenger - charged that accusations of corruption had hurt Malta’s financial services industry and would continue to damage the Mediterranean island’s reputation.

Muscat says has done nothing wrong, and has pledged to resign if the inquiry concerning him and his wife, Michelle, reveals any link to the company opened in Panama.

During the campaign, he promised continuity and greater wealth for a country that has the lowest unemployment rate ever at 4.1 percent - the third lowest in Europe - and in 2016 registered a budget surplus for the first time in three decades. Muscat also championed civil rights causes, introducing civil unions in 2014.

Shortly after polls closed, Malta’s head of state, President Marie Louise Coleiro Preca, called for a process of reconciliation to begin after what she called a campaign full of “aggressive and abusive language” both by politicians and the public alike.

“I want to see people returning to open dialogue, which is the basis of a healthy democracy,” she said.

There are no exit polls and counting of votes will be carried out manually starting Sunday morning. Results are expected later Sunday.
