Labour is urging its voters not to back Brexit
Many Labour voters do not know the party backs remaining in the EU and it could lead to a Leave vote in the referendum, senior party figures have warned.
Former leader Ed Miliband said the referendum result was "in question" and urged Labour supporters not to use it as a protest vote against the Tories.
The party's top brass is warning Labour voters would be hit hardest by Brexit.
