Leaving the EU is a risk for British businesses according to Lord Rose, chair of Britain Stronger in Europe - which supports continued EU membership. <br />Speaking to the Today programme, the former M&S boss quoted research, from the Centre for European Reform, which suggests the effect of EU membership in 2014 was worth a total of £133bn to 200,000 British firms that import and export. <br />He told presenter Justin Webb that he was "a bit of a Eurosceptic" himself and that there were "imperfections" with the EU but by and large it worked. <br />"Leave" campaigners have claimed support from new research by the independent think tank Civitas, which said membership of the single market has not had a significant impact on export growth.
