DAVID CAMERON faces an embarrassing EU referendum delay over his refusal to allow 16 and 17-year-olds a vote, Labour predicted yesterday.

However, doing so could set back the vote further if Labour and Lib Dem peers reinstate it when it returns to the upper house and further “ping-pong” continues.
