In a pregnant pause as Black Rod relayed Her Majesty's summons for her MPs to attend her in the Lords, the unmistakable voice of former working miner Dennis Skinner chirped up:
Who shot the 'arriers..?It seemed an obscure comment which totally missed its target...
But a couple of hours later the mystery seems to have been solved with this story about a police investigation into the shooting of two 'protected' wild birds on the Royal Sandringham Estate.
Prince Harry, a mate and a local gamekeeper were on a shooting party on the same day as the birds were shot. Allegedly.
The Royal party say they didn't shoot the 'arriers.
And police say there is not enough evidence to bring charges against anyone. Anyone convicted of shooting the protected birds risks a £5,000 fine or six months clink.
Seems we'll never know the answer to Dennis's rather timely intervention...
