The introduction of such a tax, which could mean Islanders would have to pay tax on the sale of property and businesses, could be the ‘sting in the tail’ of Europe’s ruling on zero-ten, says Richard Murphy, of the Tax Justice Network.

He said that a source within Europe had told him that tax officials were still not happy with changes Jersey had made to the its zero-ten company tax policy.

However, Treasury Minister Philip Ozouf dismissed the claims as nonsense. He said that Mr Murphy would not stop attacking Jersey until it was fully integrated into the UK and that he had been proved wrong many times in the past.
