Hungarian Prime Minister Viktor Orbán has been criticised for wearing a scarf that features a historical map of "Greater Hungary".Orbán's decision to display the map at a public event has been criticised by two of Hungary's European neighbours."The promotion of revisionist ideas in Hungary does not contribute to the development of Ukrainian-Hungarian relations and does not correspond to the principles of European politics," ministry spokesperson Oleg Nikolenko wrote on Facebook."The Hungarian ambassador will be invited to the Ukrainian foreign ministry and made aware of the unacceptability of Viktor Orbán's actions."Orbán has previously been accused of provoking tensions over the large ethnic Hungarian community, who live in the Romania region of Transylvania."
