Prince William is expected to play an important role in his brothers upcoming nuptials. That is, if Prince Harry ever gets around to asking him.

During a discussion on Wednesday, radio host Roman Kemp asked the Duke of Cambridge about serving as best man at Harry and Meghan Markle s wedding this spring.

He hasnt asked me yet , just to clear that up. It could be a sensitive subject, the royal quipped , according to People.

William also brought up another problem he has with the wedding, which is supposed to take place on Saturday, May 19 . That also happens to be the date of the finals of the Emirates FA Cup, an annual tournament for English soccer teams. William has been the president of The Football Association, organizer of the tournament, for over a decade. He typically presents the trophy to the winners of the final.

William joked that hes still working through the conflicting engagements.

[Im] trying to see what I can do, he said.
