Come on Colwyn your not surprised at Osborne trying to get lower Corporation Tax through under the disguise of 'necessary' in the post Brexit world. He has previous in putting through many right wing economic fiscal policies under the same banner as 'necessary' because of Austerity, look at the cut in the 50% tax rate for the rich for example, and the only people that fooled was their patsy coalition partners the Lib Dems. Out of Eu should not mean off shore, but then again the Irish, Dutch and Luxembourg (by Junker) have made an industry out of it, particularly the Irish. When that EU ignored nonsense started you knew it could only end in a race to the bottom of corporate taxation rate, and as you rightly say how do you fill that taxation rate.
