May I say to you, Mr. Speaker, in your last Question Time, that it would not come amiss from me and from my colleagues below the Gangway, to thank you for the part you played in getting my right hon. Friend the Chancellor of the Duchy of Lancaster to come along and answer Questions? While I am about it, may I ask my right hon. Friend whether he accepts that what he has managed to achieve in negotiating this participation with various oil companies has been a relatively easy exercise up to now, because he has been negotiating, by and large, with Government Departments directly or indirectly in the name of BP, Burmah Oil, and the NCB-controlled areas? What will he do if, for example, American or German companies refuse to accept participation, in contrast with the cases that he has already dealt with?
