They tried. Lasted 40 days, almost tanked the pension funds and the pound. You can not build a democratic Singapore, there are too many socialists and open communists in the UK and soon they will have a majority in the parliament. So trust my word, in 1-2 years there will be general election, Labour will win and they will abolish non-dom, raise taxes for corporations and "rich" people alike, print money to cover the holes in the budget and run the country to the ground. In 5-10 years they will again lose to Conservatives and the cycle continued.
