Charles Moore's column "No offence to sailors . . .", Daily Telegraph 26th November. Was this article fake or a mistake?

I often read Charles Moore’s column on the Daily Telegraph’s website and usually agree with his opinions.  Be that as it may, on Sunday the 26 November I was startled and amused at his reference to Penny Mordaunt, a Royal Navy reservist, as the Defence Secretary!  In fact she is the Secretary of State for International Development. Was this article fake or a mistake?

The article “No offence to sailors, but they are only guarding Buckingham Palace because there aren’t enough soldiers” bemoaned the “parlous state of our Armed Forces” and doubted that using personnel from the Royal Navy to change the guard at Buckingham Palace was an efficient use of resources.  Mentioning Penny Mordaunt, and giving her the wrong title, rather detracted from the thrust of the argument.

The mistake was corrected the next morning with Ms Mordaunt back at the DfID!  Nevertheless, it still seemed not really relevant for Mr Moore to mention her.
 

When all is said and done, I cannot see much wrong with the Navy, or the RAF for that matter, performing guard duties at Buckingham Palace.  They, and the Army, are part of Her Majesty’s Armed Forces - whether in a parlous state or not!
