The European Parliament has stripped a Greek MEP of her role as one of the body’s vice presidents over allegations that Qatar had bribed her to influence decision-making.

Eva Kaili, 44, one of the parliament’s 14 vice presidents, was among four people arrested and charged by investigators in Belgium over the bribery and corruption scandal.

It comes after European Commission President Ursula von der Leyen said on Monday that the allegations claiming they had received money and gifts from Qatar were of the “utmost concern”.

Belgian police searched 19 homes and parliamentary offices in raids from Friday to Monday as part of their investigation and seized computers, mobile phones and cash, some of which was found in a suitcase in a hotel room.

Prosecutors said they had suspected for months that a Gulf state was trying to influence decision-making in Brussels.

They did not name the suspects, but Ms Kaili’s name was leaked to the media.

Ms Kaili, who denies the charges, was suspended from her duties in light of the investigation at the weekend, while the Greek socialist PASOK party announced it was expelling her from its ranks.

A source with knowledge of the case told Reuters news agency the state was Qatar.

Qatar has denied any wrongdoing.

A total of 625 MEPs voted in favour of stripping Ms Kaili of her title, with only one against and two abstaining.

“The integrity of @Europarl_EN comes first and foremost,” European Parliament President Roberta Metsola tweeted.

Scandal risks damaging EU’s image

The vote to sack Eva Kaili was a very rare sign of (near) unity in the European Parliament.

It marks the latest stage in a quite stunning fall from grace.

A week ago, Kaili was seen as a dynamic figure with a particular interest in digital technology; a former TV news presenter who had been elevated to being a vice-president of the parliament.

Now she is in detention, linked to corruption and her career is in ruins. And all the smoke signals point to a direct link between Kaili and Qatar.

She recently told the parliament that Qatar was a “front-runner in labour rights”, despite the deaths of migrant workers building football stadia, and berated colleagues for bullying the country and showing discrimination.

Instead, the criticism of Qatar is now about to increase.

Later today, the European Parliament will hold a debate on the suspicions of corruption “from Qatarā€¯” (note that wording: “from Qatar” rather than “in Qatar” – this is about Qatari influence outside the country) as well as the need for more transparency in European institutions.

And that’s where the parliament will have to look at itself – it’s long been accused of being too opaque in its regulations, with many MEPs having second jobs and lobbying firms floating around like dust in the air.

The question of where lobbying ends and corruption begins is an old one – but now might be the time when the parliament starts to take it much more seriously.

Ms Kaili’s lawyer, Michalis Dimitrakopoulos, said his client was “innocent”.

“She has nothing to do with financing from Qatar, nothing, explicitly and unequivocally,” he told Greek broadcaster Open TV.

In a speech in the European Parliament on 21 November as the World Cup was starting, Ms Kaili said: “Qatar is a frontrunner in labour rights.

“They committed to a vision by choice and they opened to the world. Still, some here are calling to discriminate them. They bully them and they accuse everyone that talks to them or engages (with them) of corruption.”
