I agree, it's something I've been worried about for years as I see housing, businesses, including what once were our nationalised industries, and other businesses, being sold off to foreign investors, and I even saw a news item about our local councils hosting an event to sell off council land which was attracting attention from overseas investors. Selling England by the pound to quote a genesis song!!
If the rest of the world thinks we are such a good buy why are there not more British buy offs to keep things in house so to speak and protect our future incomes.
