Anything which can be done to create a tax based on 21st-century policy aims, to simplify the legislation, to reduce the need for ordinary families to have to engage in complex tax planning, and to reduce the burden of administration will be welcome. While I very much doubt that we will see the fundamental review which is necessary, it is good to travel hopefully. When the terms of reference are published I will be scrutinising them in detail.
