I certainly do not know the number of companies operating under the previous rules, but I would be happy to drop the hon. Lady a letter with any number that HMRC may have that can be publicly disclosed. The point is that there is a relatively small number of companies; they have seen this coming and it is an optional advantage for them. In reply to the point raised by the hon. Member for Ilford North, it applies only during the transition period, which will end at the end of this year.
We will be leaving the transition period on
The hon. Member for Ilford North also raises an important question about whether there is enough time for business to accommodate rules. I cannot comment on behalf of other Departments, but it certainly is a concern that has been raised in relation to the creation of tax law. Wherever possible, the Government try to abide by rules that we introduced after 2010 in order to have a more effective tax process. As he knows, it involves several stages and periods of consultation. We are coming up to an L day for legislation to be considered for the 2020 Budget, for the autumn Budget—if there is one—and for a Finance Bill next year. There is an orderly process, but I take his point about the importance of ensuring that it is as orderly and well structured as possible.
