The lawyer for Greek member of European Parliament Eva Kaili on Tuesday said his client was "innocent" after she was charged with corruption in a probe into suspected bribes from Qatar.
Belgium has charged four suspects including Kaili as part of an investigation into allegations World Cup host Qatar has been handing out cash and gifts to influence EU policy debate.
Two others were released after questioning.
"Her position is she is innocent. She has nothing to do with Qatar's bribes," Kaili's lawyer Michalis Dimitrakopoulos told private Greek television channel Open TV.
Belgian prosecutors said 600,000 euros ($630,000) were found at the home of one suspect, 150,000 euros at the flat of an MEP and several hundred thousand euros in a suitcase in a hotel room.
Asked if any cash was found at Kaili's home, Dimitrakopoulos said: "I am not confirming or denying. There is confidentiality. I have no idea if money was found or how much was found."
Kaili, a 44-year-old Greek socialist and one of the European Parliament's vice-presidents, was detained in Brussels on Friday.
She has been stripped of her vice-presidential responsibilities and parliamentary group leaders are to meet Tuesday to prepare a vote to formally remove her from the post.
She is remanded in custody and will face a hearing on Wednesday to see if she and three fellow accused will need to remain in detention pending a corruption trial.
