The UK's Migration Advisory Committee (MAC) has recommended that there should be changes to the Tier 1 (Investor) visa because they say it is of questionable benefit to the UK taxpayer. One of their recommendations is that the UK should auction off 100 premium investor visas each year in a sealed auction.
The UK has had an investor visa since 1994. The Tier 1 (Investor) visa was instituted as part of the UK's five-tier visa system in 2008. The MAC's chairman, Professor David Metcalf has previously questioned the value of the Investor visa route.
