Robert Fico, who has served as the country’s prime minister since 2012, said the brutal murders were an attack on European identity, adding that it was imperative the public knows it as such. He said: “We consider that attacking people at Christmas markets, who to some extend are preparing for Christmas, os an attack against the cultural identity of Europe.

“We need the public to know that these attacks that are taking place and that they are attacks against European identity.” Referring to mass migration, Mr Fico also gave a stark warning to complacent EU leaders that across the continent “the cup of patience is beginning to spill over”. He added: “The public in Europe will, legitimately, expect considerably more vigorous measures to ensure that they can spend their free time in peace.”

The leader also reasserted his record as an ardent skeptic of mass migration, and pledged to stick with policies which would ensure the safety of the Slovakian people. He said: “I think the measures we have taken as a result of the migration crisis were absolutely right, and I believe that in a short time they will prove to have been necessary.” Mr Fico, a tough critic of Islam and jihadi extremism, also said he would “never agree to develop a Muslim community in Slovakia” for as long as he is prime minister.

The 52-year-old, who has served as Slovakia’s prime minister for a decade in total, with a two-year-gap between his times in office, has been one of Europe’s staunchest resistors of mass migration policy and so-called “Islamisation”. Last month, Mr Fico blasted the EU’s migrant quota scheme set up by clueless Brussels overlords, and described the policy as “dead”.
