AlHijjah 7, 1436, Sep 21, 2015, SPA -- The Liberal Democrats, Britain's most enthusiastic Europhiles, kick off the fight to stay in the European Union on Monday with a warning that its rivals are dangerously ambivalent about the consequences of leaving, Reuters reported. Nick Clegg, the former party leader and coalition partner of Prime Minister David Cameron in the last government, will say the stakes "could not be higher", with a "Brexit" potentially leading to a break-up of the United Kingdom. Britons will vote on the country's future in the 28-member bloc before the end of 2017 in a referendum Cameron promised before last May's election to try to counter the rise of the anti-EU UK Independence Party. The LibDems, who were reduced in that election to only eight lawmakers after 57 in the last parliament, previously could have counted on the opposition Labour Party to back the EU. But Clegg will say the election of left-winger Jeremy Corbyn as Labour leader this month has muddied the waters. "I say to Jeremy Corbyn: the EU referendum is simply too important for ambivalence, " he will tell delegates at the party's conference, according to extracts from his speech. -- SPA 03:46 LOCAL TIME 00:46 GMT تغريد
