Next week, as chair of the British Group of the Inter-Parliamentary Union, I will be welcoming the first delegation of Iranian parliamentarians to visit this country for some time. Will my hon. Friend welcome that development? He knows not only that the House will give full and appropriate courtesy to parliamentarians from Iran, but that it will take the opportunity to engage them in the full and frank discussion of matters between us, which is the only basis on which parliamentarians can build a relationship.
