The Belgian transport minister has resigned over accusations she ignored lapses in security at Brussels airport before the attacks of 22 March.
A confidential document showed security lapses at Belgium’s airports were identified by EU inspectors in 2015.
Minister Jacqueline Galant had denied having seen the report, which was leaked by opposition parties.
Attacks on Zaventem airport and a Brussels metro station by so-called Islamic State left 32 people dead.
Prime Minister Charles Michel had previously defended Ms Galant, and he had told parliament that her office had not seen the critical EU report.
However on Friday morning, following the publication of further documents on Thursday evening, Mr Michel said that “contrary to what was communicated to me” the report had been discussed, according to public broadcaster RTBF.
