If leaves wins, we will 100% be leaving the EU.
I've seen it suggested that even if "leave" wins your Parliament will simply refuse to act on the results.The state legislature of my state,Massachusetts,has done this at least once...when voters voted to lower taxes.They simply ignored the results.
Don't know if your Parliament might try that or if would be legal to do so.
I have my doubts on that, especially if the vote is close
Could MPs block an EU exit if Britain votes for it?Michael, from East Sussex asks an intriguing question - could the necessary legislation pass the Commons if all SNP and Lib Dems, nearly all Labour and many Conservative MPs were in favour of staying?
The answer is that technically MPs could block an EU exit - but it would be seen as political suicide to go against the will of the people as expressed in a referendum. The referendum result is not legally binding - Parliament still has to pass the laws that will get Britain out of the 28 nation bloc, starting with the repeal of the 1972 European Communities Act.
The withdrawal agreement would also have to be ratified by Parliament - the House of Lords and/or the Commons could vote against ratification, according to a House of Commons library report.
I think there is a lot riding on this vote; perhaps the most important vote in the history of mankind.
