Speaking outside the Russian embassy in Budapest in the wake of the Skripal poisoning scandal in the UK, Tamas Soproni went on to ask for a ban on Russian propaganda in Hungary.

According to AP he also said, "Hungary should terminate the contract for Russia's expansion of Hungary's only nuclear power plant and said all details of Russia's loan of 10 billion euros (approx. 12.3 billion US dollars) for the project should be made public".
