Behind a unmarked maroon entrance in central London is one of London’s most exclusive, influential private clubs. Members include politicians and celebrities as well as royals. 

5 Hertford Street, located on the corner of Shepherd Market in Mayfair, is owned by millionaire aristocrat and Tory donor Robin Birley and often considered one of the most secretive in London. 

The club hit headlines after Foreign Secretary Liz Truss requested departmental funds to host a £3,000 lunch while wining and dining Jo Biden’s trade representative at the club. 

The venue suffered six-figure losses and was also the first meeting place for Prince Harry, Meghan Markle, and the Duke and Duchess of Cambridge.  

Membership is utterly exclusive, with two recommendations from existing members necessary for approval, and while the club have not publicly revealed their annual fees, it costs £1,800 annually. 

Guests can descend down a steep flight of stairs into the opulent basement club Loulou’s – featuring the venue’s beloved giraffe’s head mascot – loved by A-listers and royals alike.

‘King of clubs’ Robin Birley (pictured) took the extraordinary step of spending millions of his own money to lure members back to his fashionable Mayfair nightspots last year 

He is the half brother of Environment Minister Lord Goldsmith of Richmond Park and donated £20,000 towards Boris Johnson’s leadership bid. 

Last year, Robin Birley took taken the extraordinary step of spending millions of his own money to lure members back to his fashionable Mayfair nightspots.

He gave every member of 5 Hertford Street and Oswald’s a free meal up to the value of £500 — that’s more than the net weekly salary of the average Briton.

At the time, a friend told Richard Eden: ‘Robin thinks the members have been so wonderfully loyal to the club over the past few months that he wants to show just how much he values their support,.’

There are understood to be at least 3,000 members of the two clubs so it could set Birley back more than £1.5 million.

Whitehall mandarins tried to stop Liz Truss wining and dining a US diplomat and eight others at a Tory donor’s Mayfair club to save just £400 on a lunch bill. 

The Foreign Secretary ‘overruled officials’ and ‘explicitly asked’ to use 5 Hertford Street in central London, owned by millionaire aristocrat Robin Birley, before spending hundreds of pounds on gin and wine alone.

In June, Ms Truss requested departmental funds to host a £3,000 lunch at the venue with Katherine Tai, Jo Biden’s trade representative, while International Trade Secretary. 

Reports The Sunday Times that Ms Truss reportedly “refused” to consider other options for lunch. 

The bill’s savings are being made just months after the Foreign Office was accused of attempting to reduce costs by allowing civil servants at other departments to be blamed for failing to grasp the gravity of August’s Afghanistan evacuation crisis.

A whistleblower cited an eight-hour shift culture and the refusal to work weekends as reasons for failures that led to Afghan civilians being ‘left behind and murdered by the Taliban’. 

Sarah Healey, a top civil servant and permanent secretary to the Department for Digital, Culture, Media and Sport, is also being accused of undermining attempts by ministers to bring back officials last year. She had praised the advantages of working remotely because she could ride her Peloton bicycle.  

However, the rules regarding lunch were followed by civil servants from the Department for International Trade. They said that they were so worried about the cost of the event and its links to Tory parties, they suggested Ms Truss to the permanent secretary, the highest ranking official in the department.  

Its owner, Mr Birley, is the half brother of Environment Minister Lord Goldsmith of Richmond Park and donated £20,000 towards Boris Johnson’s leadership bid. 

It has been used also by Foreign Secretary 46 to host meetings called ‘Fizz With Liz’ to mingle with Tory MPs as well as ‘Biz for Liz’ events to meet potential financial backers for his leadership bid.
