Health and Care Bill

In passing, may I congratulate my right hon. Friend on his appointment? I also very much welcome part 4 of the Bill, which introduces the health services safety investigations body. This is a great innovation that was promoted by the Public Administration Committee and scrutinised by the Joint Committee that I chair. Can I just reinforce the points that I know he is now receiving from NHS England with a warning about changing the boundaries of the integrated care systems that are already operating? In Suffolk and north-east Essex, we have a very high-functioning de facto integrated care system operating already. Please will he not change it?
