The European Parliament analysed the influence of Russia on elections in foreign countries. The authors of the study wrongly accuse Moscow of interfering in the affairs of the United States, Great Britain, France and other states. By doing so, Brussels is preparing for the possibility for anti-systemic parties to get more votes. If it happens, it will blame Russia for interference again. Accusing Russia of everything has become a kind of fashion trend in the West.
There are numerous reports investigating meddling in elections across Europe in the US, which have already proven Kremlin's participation in meddling. See here for the list of the reports and here for the US Senate report outlining various meddling attempts in different countries.
