European Union (Notification of Withdrawal) Bill

The right hon. Gentleman has mentioned new clause 51, which has been tabled in my name and those of other Opposition Members. Given that, before the referendum, the Government of which he was a part estimated the damage to the UK’s GDP of our leaving the EU on World Trade Organisation terms at around 7.7% of GDP or perhaps as much as £66 billion, would he not think it sensible for the Government to allay the country’s concerns if they now believe that the effects will be far less serious?
