As far as the Queen is concerned, nothing but the best will do for her beloved corgis.

Indeed, staff often joke that her pampered pets eat better than the human members of the Royal Family.

And last week, she was shocked to find that the dogs’ supposedly freshly cooked meals were actually frozen and reheated.

According to sources, the Queen, who is on holiday at Balmoral, was furious when she made the discovery while dishing up her pets’ supper one evening.

So fond is the Queen of her dogs that she insists on serving their supposedly chef-prepared dinners herself.

But on this occasion it became apparent that the meal had been frozen as it had not properly thawed in the middle.

‘Quite simply she went bonkers,’ one royal insider told the Mail.

‘The Queen was half way through dishing out best quality cooked meat to her beloved dogs when she realised the centre of the dinner had not defrosted properly.

‘For years she has always demanded that all food for corgis is 100 per cent fresh, and when she found out that cooks had not been following her instructions she let her feelings be known.

‘A footman was summoned and told to go down to the kitchens where the chefs on duty were torn off a strip.

‘They were told in no uncertain terms that it should never, ever happen again and that all food had to be fresh. The chefs were acutely embarrassed and didn’t know what to say. Obviously one of them had been far too casual in his attitude and had just thought it was for the dogs, so it didn’t matter.

‘But he clearly didn’t know what they mean to the Queen.

‘Goodness knows if it was a one-off or if batches of food have been frozen and served up as fresh for years.

‘If the Queen finds out that is the case then heads may roll.’
