UK’s Withdrawal from the EU

I have been listening with some interest to the right hon. and learned Gentleman’s explanation of the five bullet points that are so important in the Leader of the Opposition’s amendment, but most of them are fundamentally to do with the future phase of negotiations and are not specifically to do with the withdrawal agreement Bill. I am therefore still puzzled about what the major difference is between his party and the Government and why it cannot agree with the Government to secure the withdrawal agreement and get it through Parliament.
