The killing of the Labour MP and Remain campaigner Jo Cox has meant that all lobbying for votes before Thursday's referendum has been suspended.
High profile visits and debates in Kent, Essex and Sussex were cancelled as a mark of respect.
Nevertheless, turnout in the referendum is expected to be high. It'll be especially high among older voters - with some younger voters unlikely to take part.
We found three young voters who say they are determined to vote but haven't made up their minds yet. So we took them to meet two successful businesses in the South East to see if that would affect their decision.
