On a point of order, Mr Speaker. Since you took the Chair, you have been a stalwart defender of Back Benchers. You have also stood up to bad parliamentary behaviour like the use of the word “racism”. I am deeply upset that your chairmanship has been undermined dramatically because of the very calm and polite advice you gave to hon. Members—leaders of political parties—that was ignored. Please will you do all you can to ensure that words such as “racist” are not common parlance in this House?
