Kate did not confirm she was attending Trooping the Colour until the day before. She has to take things a day at a time with chemotherapy. “I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days,” she explained. “On those bad days you feel weak, tired, and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well.” She hopes to make a few more appearances this summer.

Debbie Jevans, the All England Club chair, is hoping one of those outings will be to present the trophies at Wimbledon, as the princess has done in the past. “We’re hopeful that the Princess of Wales will be able to present the trophies as the Club’s patron, but her health and recovery is the priority,” Jevans explained to Telegraph Sport. “We don’t know what we don’t know. All we’ve said is that we’ll work with her and give her as much flexibility as possible.”
