Tory black-tie party goes all hush-hush . . .

Cabinet ministers are on a threeline whip to attend the most lucrative event in the tory social calendar. but yet again the party leadership would rather no one noticed the annual black & White Party is taking place on Wednesday at the natural History Museum.

there’s not a word about it on the tory website, and the museum refuses to discuss the event, where tables fetch up to £15,000.

the thrash, which is being organised by George Farmer, a twentysomething former member of the notorious bullingdon Club — to which David Cameron and boris Johnson belonged at Oxford — is a sell-out.

at least the tories under theresa May are reverting to tradition with the dress code. When Cameron was PM, guests were asked to wear lounge suits and cocktail dresses — so as to make the party seem more inclusive.

Wednesday will be black tie. ‘Such a relief,’ sighs my mole at Conservative HQ. ‘We all had to be achingly cool under Dave Cameron. Our supporters found it all very confusing.’

a tory treasurer, Dominic Johnson, who loaned Cameron his £4million Chelsea home for a year after his abrupt exit from Downing Street, no doubt hopes for the event to be a financial success.

Hedge fund financier Johnson — nicknamed Uriah Heep after the Charles Dickens character noted for his cloying obsequience — apparently wants a peerage.

‘He was disappointed not to get one from Cameron,’ says my source. ‘He’s hoping to be on the next peerage list, but hedge fund types are not flavour of the month in theresa’s office.’
