There's no problem with holding another referendum as long as it's a straight choice between May's deal and no deal. If Corbyn had any balls that is the referendum he would promote, but of course we all know that any second referendum would just merely be a re-run of the first. This is not a 'People's Vote', this is a Loser's Vote.
Remain should not be an option. We already had that vote and Remain was rejected.
