UK Borders Bill

As my hon. Friend knows, the Select Committee on Home Affairs, under successive Chairmen, has supported the broad principle of a border force. He has set out the reasons why he does not want to do that now, but would it not be sensible to use the Bill at least to align the powers of immigration and customs officers, so that our front-line staff at the borders have the same sets of powers and can be used interchangeably on different operations? Short of a border force, that would allow much more flexible use of our vital front-line staff.
