Could the NHS cost the Tories or is Jeremy Corbyn too unpopular to win it?

New figures out today show more patients than ever waited longer than four hours in A&E in England during October. Labour's seized on the data, saying the NHS was in crisis - but Boris Johnson says Labour would "rack up such colossal debt" that it would be impossible to invest the money needed into the health service. With the NHS high up on many voters' key priorities, will today's figures see support switch away the Conservatives and to Labour? Robert gives us his take. Labour leader Jeremy Corbyn has been heckled for a second day in a row during his visit to Scotland. Our correspondent Libby Wiener has been following Mr Corbyn - we chat to her about how the party's campaign in Scotland is going so far. Plus some very important discussion about what really is the right way to make a cup of tea, after a Tory campaign video showed Boris Johnson adding milk to his cup of tea BEFORE removing the bag.
