The right hon. Gentleman will be aware that the Government also have concerns about the Paris climate change agreement, and we think it greatly to be regretted that the US decided to withdraw from it. I reiterate that it is important to recognise that the US has not yet withdrawn from this treaty, and it is the work of allies—particularly here on the European continent, and not least the big three of the United Kingdom, Germany and France—to try to exert as much pressure as possible in that regard. The easiest way to resolve this matter is to ensure that the bilateral arrangement that has been in place for 31 years is adhered to by one of the parties that is not doing so. In a way, this is frustration boiling over, and as I have pointed out, this is not something new to the Trump Administration; this high-profile issue goes back almost half a decade, including during the Obama Administration.
