Apologies if this point has already been made, but if the main part of the security bill is for covering the carriage ride through Windsor to protect members of the royal family, surely only Prince Harry and his bride went ride-about after their wedding? All the other guests went straight to the reception, therefore no need for immense expensive protection outside the castle walls.
I am a strong supporter of the concept and reality of our royal family, but I wouldn't cross the road to see any one of the four members of the York clan. I was mildly pleased to hear that Eugenie was getting married as I thought at last she could escape the stifling environment of her mother and sister and lead her own life, as all the other minor royals do, ie the children of the Snowdens, Kents, Gloucesters and Phillips. Regrettably, it appears she intends to continue stressing her royal credentials whilst doing nothing to justify her place.
