Sabotage of the EP, an important diplomatic body known for applying pressure to hostile regimes or those that engage in human rights abuses or anti-democratic behaviour, threatens to blow up into a major crisis at the heart of the European Union.
In the Sunday statement, a diplomat from Qatar's mission to the European Union reiterated a previous rejection of attempts to associate the Gulf country with misconduct.
A Qatari official, who said that he was not aware of any details of the investigation, said, "Any claims of misconduct by the state of Qatar are gravely misinformed."
