I am grateful to my right hon. Friend for those excellent points. They highlight one reason why the merging of the Department for International Development with the Foreign and Commonwealth Office to form the Foreign, Commonwealth and Development Office has the potential to link those two areas of policy. The challenge with push factors is substantial and it is that they have only just started. He is right to refer to malign actors such as Russia in the short and medium terms, but there is a much bigger factor that this House needs to consider over the next 20 to 50 years: climate change. The likelihood is that there will be very significant mass migration from sub-Saharan Africa when large areas of countries, perhaps entire countries, may become functionally uninhabitable through water scarcity and heat. What we have seen currently in push factors will be nothing compared with what we see in the future, so it behoves us, as a responsible Government, to design and implement an immigration policy that is fit for purpose, not just for now, but for the future.
