And then, once she's negotiated a deal that doesn't have May's red lines, agrees said deal with the EU, she will present this new deal to Parliament and the public... and then tell everyone not to vote for it.
If she wanted to be honest with people, she should just say "No, if in power I would not renegotiate with the EU, I would revoke A50 and we'd stay in the EU". That is her actual position but she knows it's not popular and would lose her party votes in a GE, which is why she won't come out and say what she really feels, but she exposed her true position last night, finally.
She just wants Labour in power, she doesn't give a flying fuck about respecting the referendum result or leave voters.
