And he will focus on changes to the Schengen visa system that are being put in place but has admitted the security measures being introduced will never ensure 'zero risk' to the public and that they're "not perfect". Oxford educated Julian King, who was appointed by Jean Claude Juncker, will deliver a speech on "Priorities and Challenges for the Security Union" at the 41st meeting of the Christian Social Union Bundestag faction in Berlin on January 5, it has been confirmed. The CSU is sister party to Merkel's Christian Democrats (CDU), and together they form "The Union". It is believed Mr King will also discuss the issue with German Chancellor Angela Merkel who has agreed to work with Bavaria's Christian Social Union to focus on common interests ahead of national elections next year.

Mr King is expected to outline the background to the history of free movement which was first put forward back in 1957.

Europe has a mandatory asylum and immigration policy but that has led to significant backlash after a catalogue of terror attacks across France, Belgium and Germany. In a speech delivered on Wednesday ahead of his trip to Germany Mr King said: "Our thoughts are with all of those who have lost someone they loved in the terrible attack in Berlin and our solidarity is with all those affected. "More generally, those who commit these attacks seek to destroy our way of life and our values. But we should not give them satisfaction, we should not stop living our lives. "The French authorities were right to go ahead with the Euro2016 championships this summer, so are the German authorities when they allow Christmas markets to go ahead.

"But we can't ignore the risk that exists. There can never be 'zero risk'. "We can and must continue to reduce the risk of attacks as far as we possibly can. "National, regional and local authorities are in the front line to both prevent attacks and to deal with the aftermath when they happen - but by standing together, we can be stronger.

"It is particularly important when some foreign terrorist fighters – as well as non-combatants - may decide to try and return to Europe as some of their strongholds weaken. "We've also made progress strengthening our security behind our borders – we are working on improving the effectiveness of the various databases we have and how they work together because we are only as strong as our weakest system or database. "We also need to hit the terrorists where it hurts them: making it harder for them to travel, to train, to finance themselves, to acquire the weapons and explosive they are looking for. "We've agreed a deal on firearms – it's not perfect, but it will remove the most dangerous military grade weapons from wider circulation, where they have no place.

"And we've agreed the counter-terrorism directive - travel to and from combat zones, training for the purposes of fighting and the financing of such activities will now be criminalised across the EU."
