United Kingdom

Two-thirds of Labour voters voted for Remain in the Referendum.

Younger voters, who are the most likely to vote Labour, but the least likely to get to the polls, are overwhelmingly Remain voters. If they had voted in the referendum in the same proportion as older voters, Remain would have won. A Remain-supporting Labour party would be likely to attract more under-25s to the polls, than one not committed to Remain.

Also: it seems somewhat strange to me that you condemn every compromise with the Right that Labour has ever made in order to get elected, EXCEPT this one. If you think it is wrong for Labour to compromise on the nuclear 'deterrent' or on privatization of public services, why is it OK for them to compromise on Brexit, which, for starters, will undoubtedly reduce availability of funding for public services?
