A CALL to arms to Britain's pro-Europeans has been made by Charles Kennedy, who warns the recent wave of hostility towards the European Union and the threat to the UK's membership of it is "dangerous and short-sighted".

The former LibDem leader, who is president of the European Movement UK, has used its regular euroblog to decry David Cameron's recent speech on Europe as causing a "sense of uncertainty and insecurity" among those in favour of Britain's continued membership of the EU.

Mr Kennedy claims the PM's promise of an in-out referendum by November 2017, should the Tories form the next UK Government, has resulted in many people expressing concern at the possibility of Britain leaving the EU. "His speech has focused public attention and forced frontline politicians and business with pro-European sentiments to come out and join organisations like the European Movement in defending Britain's membership of the EU," writes the MP for Ross, Skye and Lochaber.

He claims the public's attitude to Europe is now changing after years of "euromyth-infused anti-EU arguments" peddled by the tabloid press thanks to the growth of the pro-EU coalition and its articulation of the "advantages of membership".

He insists it is imperative pro-Europeans explain what the benefits of EU membership are to counter-balance the negative image projected by the tabloids, Ukip and some Tory MPs.

He warns that a British exit from the EU would have "undesirable consequences" with the UK losing "massively in economic terms".

He insists: "Britain alone, adrift in the Atlantic, squeezed between the US, the EU, China, Brazil, India and other global powers will be relegated to a bystander of world events, unable to shape history and influence its own destiny.

"Membership of a strong, confident, effective, outward-looking European Union should be an absolute priority for all European nations. Playing games with something so important is dangerous and short-sighted."
