Exiting the European Union and Global Trade

I understand and take on board everything my right hon. Friend says about the WTO and a rules-based system, but, as he observed earlier in his speech, the bulk of our economy, and the bulk of our competitive advantage, lies in the services sector, which in the case of the financial sector is not particularly covered by WTO rules. Will the Government be equally as committed to making sure that we have global liberalisation of the services sector, which is so critical to us?
