Speaker John Bercow warns MPs over comments on expenses cases now charges have been brought

"Speaker John Bercow has warned MPs not to risk "the fairness of a criminal trial or prevent such a trial taking place" for the three expenses case MPs.  In a brief statement Mr Bercow did not refer to the question of whether the MPs could claim that parliamentary privilege covered their expenses.  Instead he reminded MPs that sub-judice rules meant MPs could not raise the subject on the floor of the House."

I thought parliamentary privilege allowed MPs to discuss sub-judice cases!
