When HMY was in service, foreign politicians and the great and the good would murder their own grandmothers to be invited to a soiree on board and distance to travel was no LIMFAC; I see no difference today, especially if she is to be used by the Royal Family from time to time (giving her that cachet that an aircraft does not have). I have hosted events aboard other HM ships in my previous role and have seen contracts valued in the hundreds of millions agreed. £200 m is nothing in terms of getting an edge over the French and the Americans in terms of trade and diplomacy.
I would expect a strengthen heli-deck, RAS and other capabilities (including self-defence) to be standard. It is a pity, however, from the impressions published she does not appear to have the graceful lines that her predecessor did. And following precedent, she could be named HMY Britannia (or Lizzie McLizzie-face)
