evidence: Lord Ashcroft published the following graphic on Twitter, which shows 51% response "for Northern Ireland to leave the UK and join the Republic of Ireland" and 49% response "for Northern Ireland to stay in the UK". The graphic includes a statement that "figures shown exclude those who answered ‘don’t know’ or ‘would not vote’". This qualifying statement was not published in the Sinn Fein manifesto. [...] The more recent Ashcroft Poll survey (September 2019) is significant in that it shows a majority support for the option for "united Ireland". In its manifesto for the 2019 General Election, Sinn Fein made a statement and published a graphic that claimed there was 51% support for Northern Ireland to leave the UK and join the Republic of Ireland, without declaring that there were "don’t know" responses.
