The first condition looks impossible to achieve. I suspect it's there to highlight an undeliverable promise made by David Davis.
Labour seems to have belatedly have woken up to Brexit and probably views it as a great way to heap pressure on the Government when it's stretched.

Labour set to outline six conditions for support of Brexit Bill in House of Commons

• Does it deliver the "exact same benefits" as the UK currently has as a member of the single market and customs union?
• Does it ensure a strong and collaborative future relationship with the EU?
• Does it ensure the fair management of migration "in the interests of the economy and communities"?
• Does it defend rights and protections and "prevent a race to the bottom"?
• Does it protect national security and the UK's capacity to tackle cross-border crime?
• Does it deliver for all regions and nations of the UK?
