Queen Elizabeth's lunch guest hilariously reveals he mistakenly ate her dogs' biscuits

We all know Queen Elizabeth II loves Pembroke Welsh corgis.

So it should come as no surprise the 95-year-old monarch - who has had over 30 canine companions over the years - puts treats out for her beloved pooches during meal times.

However, apparently for then-Health Secretary Alan Johnson, he was unaware ...

Johnson hilariously "munched away" on dog treats during a lunch with Her Majesty, Robert Hardman and Paul Murphy, the Welsh Secretary at the time, in 2008.

Hardman revealed the story in his new book Queen of Our Times writing: "We were waiting for our cars and Paul said, 'What a wonderful meal.' I said, 'I loved it. I loved every minute of it.'

"As they discussed the food, Johnson mentioned that he had particularly enjoyed the cheese and the unusual dark biscuits. Paul said, 'No, the dark biscuits were for the corgis!'.

"At that point – to Alan Johnson's eternal amusement – it suddenly dawned on him that he had been munching away on dog snacks."

Whoops!
