Investigatory Powers Bill

It might well be useful for commissioners to have experience of both functions, but not at the same time and not using the same team of staff. I think ours is a relatively modest but important proposal. I am sure the hon. Lady can see that the arrangement could be clarified to create some sort of Chinese wall between the two functions. We are not suggesting that the functions be performed by separate organisations, but the hon. and learned Member for Edinburgh South West may be about to persuade us all that separate organisations are needed.
