The value of rights owned by the Queen’s property company to exploit the seabed around Britain’s coastline has swelled to £5bn after a record-breaking auction of plots for offshore windfarms.
Profits for the crown estate, which generates money for the Treasury and the royal family, jumped by £43.4m to £312.7m in the year to the end of March.

There were exceptions, like Soviet Russia, which claimed 12 nautical miles. In the twentieth century, this wider limit came into use across the world, including the UK, and it remains in place today.
The Queen’s marine domain stretches much further. It extends to the continental shelf, a
