My right hon. and learned Friend is asking me to comment on a hypothetical whipping decision on a hypothetical vote that the Government do not wish or intend us to confront. We will be voting as a House in favour of the revised deal, which will reflect elements that this House, on 29 January, said it wanted to see changed in order to be able to support the withdrawal agreement wholeheartedly. Exactly the same challenge that my right hon. and learned Friend has posed would be posed in respect of any hypothetical event on the Bill tabled by Yvette Cooper. At this stage, it is too early to make those assertions on a hypothetical situation. What we are focused on, and where our energies lie, is negotiating an agreement with our partners in the European Union that delivers on the conditions that this House set when it passed the amendment in the name of my hon. Friend Sir Graham Brady.
