Diary: Could IPA hit jackpot in move from the square?

Is the IPA sitting on a goldmine? Diary only asks after reading that two houses in London's Belgrave Square have gone on the market at £100 million and £80 million.

The square, home to Oleg Deripaska, Russia's richest man, is also the long-term home of the IPA. It has never moved because of the generous terms of its lease.

Eight years ago, when the IPA first mooted the idea of a single "supergroup" to become the voice of the UK's entire communications industry, it calculated it could raise up to £4 million by giving up the Belgrave Square lease. Intriguing to know what that figure might be now should it choose to cash in.
