French far-right leader Marine Le Pen has been placed under formal investigation over an alleged European parliament funding scandal.
The allegations were passed to French investigators who have opened a case.
The parliament suspects some €5m (£4m; $5.4m) went to assistants of Ms Le Pen’s National Front (FN) who were not working for MEPs but were actually engaged in FN party work in France.
The National Front has denied the allegations.
Ms Le Pen has also denied any wrongdoing and has said the case is politically motivated.
The alleged fraudulent payments – from 2012 onwards – concern her and several other FN MEPs.
The allegations first arose on 27 April, ahead of the second round of voting in the French presidential election.
Ms Le Pen was beaten by Emmanuel Macron.
The FN has been highly critical of the EU, rejecting its liberal, free-market agenda.
