JEREMY HUNT may have taken part in “illegal activity” by failing to declare his investment in seven luxury flats, Labour said today.

Shadow Cabinet Office secretary Jon Trickett said his party would be referring the Health Secretary to the parliamentary standards watchdog over his failure to properly declare a 50 per cent interest in Mare Pond Properties Limited.

It is claimed Mr Hunt set up the company with his wife Lucia Guo to buy seven properties in the Ocean Village development in Southampton in February.
