Mr Speaker, I am utterly mortified by the events of last week when my heckling interrupted proceedings during Prime Minister’s questions and when I challenged the authority of the Chair. I entered into an altercation with the Chair and I did not treat the Chair with due respect. That is unacceptable. I apologise unreservedly to the House and to you personally, Mr Speaker. I really wish none of this had ever occurred and I fully accept that my conduct was unacceptable.
