A tumultuous first week for the new Estonian government has resulted in the resignation of a right-wing minister after just a day in office.
The far-right EKRE party gained five cabinet positions after a strong electoral performance.
Party leader Mart Helme and his son both made alleged white power gestures at their swearing-in on Monday.
Marti Kuusik, minister of foreign trade and IT, resigned the next day over accusations of domestic violence.
The allegations against Mr Kuusik, an MP for the Conservative People's Party of Estonia (EKRE), began in media reports.
Police have since begun an investigation into the matter. He denies any wrongdoing, and regards the allegations as slander against him.
"In addition to a horrible media attack against me, the prosecutor's office decided to start a criminal investigation. In this situation I cannot work as a minister," he said in a statement.
Like father, like son: Martin (L) and Mart Helme make the OK sign - used as a "dog whistle" by white nationalists
How far right came to power
EKRE came third in the March 2019 election, picking up 17.8% of the vote and 19 seats. It joined a coalition led by Juri Ratas's Centre Party, entering government for the first time.
At Marti Kuusik's swearing-in on Monday, Estonian President Kersti Kaljulaid left the parliament chamber when he swore his oath, forcing him to salute an empty chair, Estonian public broadcaster ERR reported.
On Tuesday, Mr Kuusik's resignation was accepted, with Prime Minister Ratas saying that when family violence was concerned there was no room for justification or doubt.
In a Facebook post, President Kaljulaid thanked the prime minister, saying she hoped "it will give courage to anyone who suffers violence".
She also thanked Estonia's press for highlighting the story - echoing the support she showed for freedom of the press on Monday, when she wore a sweatshirt reading "speech is free" in Estonian to the swearing-in ceremony.
Some Estonian journalists have expressed concern that the far-right EKRE is exerting political pressure on media organisations.
At the same ceremony, EKRE leader Mart Helme and his son Martin both appeared to make a white power gesture while being sworn in.
Is the white power gesture just OK?
The hand gesture, adopted from the familiar "OK" symbol, has spread rapidly among far-right and white nationalist groups in recent years, particularly in the United States.
Its use in that way was begun by online trolls as a joke, spreading a "hidden meaning" to media as a form of disinformation. Its continued use in that manner, however, resulted in the widely-used gesture becoming connected with white nationalists.
It was used in court by the suspect in the New Zealand shootings which killed 49 people when he opened fire on two mosques around Christchurch.
Former Estonian President Toomas Ilves tweeted about the use of the "white power sign", and has actively challenged those who say there is no such intended meaning.
Former Swedish prime minister Carl Bildt echoed the concern, saying the use of the symbol by EKRE members made him "genuinely worried".
The Anti-Defamation League in the United States says the "obvious and ancient gesture" has "acquired a new and different significance" thanks to the online hoax of 2017.
"By 2019, at least some white supremacists seem to have abandoned the ironic or satiric intent behind the original trolling campaign and used the symbol as a sincere expression of white supremacy," it says.
But it warns that "particular care must be taken not to jump to conclusions" about the intent of someone using the symbol without "other contextual evidence".
Critics point to remarks made by Martin Helme in 2013 that his message to immigrants was "if you're black, go back" and that "I want Estonia to be a white country". His father has expressed concern about immigration resulting in indigenous Estonians being "replaced".
What does EKRE stand for?
EKRE has called for a referendum on EU membership, but denies being against membership itself. During campaigning the party pushed anti-immigration rhetoric and promised to slash taxes.
As part of negotiations that led to Juri Ratas remaining in power, EKRE were handed five ministerial positions: foreign trade, environment, finance, interior, and rural affairs.
