Boris Johnson compares EU's aims to Hitler's

Boris Johnson has compared the EU's aims to Hitler's, saying both involved the intention to unify Europe under a single "authority".

The pro-Brexit Tory MP said both the Nazi leader and Napoleon had failed at unification and the EU was "an attempt to do this by different methods".

Shadow foreign secretary Hilary Benn, who backs Remain, said the comparison was "offensive and desperate".

Meanwhile, UKIP leader Nigel Farage has backed Mr Johnson to be the next PM.
