BRUSSELS is poised to veto demands for emergency border controls from countries fearing mass immigration from North Africa.
France led pleas for greater sovereignty over borders as migrants fled Egypt and Tunisia at the height of the Arab Spring earlier this year.
Countries wanted to relax some of the rules that allow passport-free travel in 25 European countries.
Britain, along with Ireland, is not a part of the Schengen Agreement zone, but Tory MEPs were concerned over the implications of an exodus on immigration here via Calais.
They are calling on Prime Minister David Cameron and Home Secretary Theresa May to ensure Britain pushes for major longer-term reform of the agreement.
However, the European Commission is expected to announce proposals on Friday that fall short, saying that permission from Brussels will be required if member states wish to re-erect border crossings in the event of a crisis.
