There will be no meaningful vote in parliament as party lines will be followed by almost everybody. It will be no more meaningful than the vote to hold a referendum or the vote to invoke Article 50, in both of which hundreds of MPs voted contrary to what they knew to be in the country's best interests for fear of turning their own parties and own careers into toast.

Stated as 'fact', but presumably you mean what you believe to be in the country's best interest.
Maybe the majority of those who voted actually had the country's best interest in mind.

And remember that 'party lines' (for both Conservative & Labour) prior to the referendum were to remain as part of the EU. They have only changed as a result of the vote to leave.
