On a point of order, Mr. O'Brien. I seek your guidance because, at the start of our proceedings on Tuesday, your colleague, Mr. McWilliam, advised us that it was customary to seek the Chair's permission to remove jackets. I have served on previous Standing Committees in which matters were different and I wondered whether, before even thinking about removing our jackets, we should ask your permission. So that I do not transgress, unlike my Liberal Democrat colleague, the hon. Member for Lewes (Norman Baker)--I do not want to cause him any embarrassment at the start of our proceedings--would it be in order for us to remove our jackets this morning? I should be grateful for your guidance.
