ONE of Asia's richest men, Li Ka-shing, has come out in favour of Britain remaining in the European Union, warning that a vote to leave would be "detrimental to the UK".

"Of course, I hope that the U.K. doesn't leave the EU," said the property tycoon who counts Northumbrian Water among his investments.

The UK accounts for 37 per cent of profit at Mr Li's main company, CK Hutchison Holding Ltd, which includes Pity Me-based Northumbrian Water. The 87-year-old billionaire's portfolio of UK investments also includes mobile operator Three and Superdrug.

Mr Li has previously said that he would be forced to scale back investment in Britain if the country were to vote to leave the EU.
