Coleman later spoke to BBC News about her experience:
The Queen and I had a conversation about time-travel, and I told her I am the Doctor's assistant and we get to travel anywhere in all of time and space, to which she replied "That must be fun" - to which I replied it really is, it's marvellous, not knowing where you're going to be from one week to the next.And did she ask who the next Doctor might be?
No! Everybody else in the building has asked me who the next Doctor is, and I can tell you honestly we don't know. It's going to be a long, long search. But yes, I'm being asked that question a lot.The full interview with BBC News can be watched in the United Kingdom via their website.
