Boris Johnson today face a tough ride as he ran the gauntlet of the Question Time audience.

For the first time Mr Corbyn made clear the public will never know whether he personally wants to Leave or Remain - admitting he intends to stay 'neutral' in a second referendum rather than backing the new package he wants to negotiate with the EU.
It is the second major TV showdown of the campaign so far - after the pair went head-to-head in an ITV special earlier this week.
