Vital amendments to the EU Withdrawal Bill

The following proposed amendments to the EU Withdrawal Bill stipulate that there must be an Act of Parliament to approve the terms of the UK’s exit before we can leave the EU.
These are therefore the two amendments that are vital in order to keep our options open and give Parliament a meaningful vote.
Amendment 7
Clause 9, page 6, line 45, at end insert “, subject to the prior enactment of a statute by Parliament approving the final terms of withdrawal of the United Kingdom from the European Union.”
Member’s explanatory statement
To require the final deal with the EU to be approved by statute passed by Parliament.
 
And
 
NC4
To move the following Clause-
“Arrangements for withdrawing from the EU
Notwithstanding any powers granted under this Act, no Minister of the Crown may agree to the arrangements for the withdrawal of the United Kingdom from the European Union referred to in Article 50(2) of the Treaty on European Union until Royal Assent is granted to an Act of Parliament—
(a) authorising the Minister to agree to an exit day to be specified in the Act,
(b) authorising the Minister to agree to those arrangements that will apply after exit day, the arrangements to be specified in the Act.”
Member’s explanatory statement
This new clause would ensure that a separate Act of Parliament would be required for Ministers to determine exit day and to set out the arrangements that will apply after exit day.
