It is well known in England’s Royal Court that Her Gracious Majesty is not one to forego life’s little pleasures. Although the Queen’s daily consumption is very modest, her doctors have nevertheless advised her to stop drinking her “evening martini” in order to ensure she is fighting fit for the forthcoming celebrations of her platinum jubilee, honouring her 70 years on the throne, on 6 February next year.
Therefore, this is a medical opinion that the Queen herself has committed to respecting, even if her entourage think the injunction is perceived as too drastic. A Court insider apparently said: “It’s not really a big deal for her; she is not a big drinker, but it seems a trifle unfair that at this stage in her life, she’s having to give up one of very few pleasures”
Let’s at least wish a splendid jubilee to the world’s most famous queen and the longest-reigning living monarch.
