Local Government Finance Bill

I am grateful to the Secretary of State for giving way on the point about tax increment financing schemes, of which I have been a strong supporter from the outset. Will he confirm that the area and rate take in the TIFs area will be ring-fenced and protected from levies and any reset? Without that confirmation, there will not be the confidence and certainty about the revenue stream necessary to allow the borrowing to take place for the up-front investment.
