My hon. Friend is making a very strong point about taxation returns and the problems in Northern Ireland. Does he agree with me that some of the simplest solutions can be the best? Some of the best tax regimes are in places such as Hong Kong where there are flat taxes, which are simple and elegant. He talked about some of the complications in the US, which has a tax code that runs to some 75,000 pages, so it is said, whereas the UK’s had about 17,000 pages in 2015.
