The table plan shows:
*Peter de Putron, an offshore financier who is brother-in-law of financial services minister Andrea Leadsom, was seated with health secretary Jeremy Hunt and Jersey’s Treasury minister, Philip Ouzouf.
None of the three men have confirmed their attendance, though Mr Hunt was photographed arriving at the event.
*The then culture secretary Maria Miller’s table included several people from the luxury yachting world including a yacht architect, the managing director of a shipyard and an interior designer for boats.
Ms Miller, who was also pictured outside the venue, has made no comment.
*Development secretary Justine Greening was listed as sitting with with two executives from Salamanca Group. Salamanca was training diplomatic protection officers in Libya under a contract with DFID at the time of the event.
A DFID spokeswoman said: “DFID ministers had no role in contractual negotiation or sign-off with Salamanca Group. DFID contracts are awarded in accordance with rigorous procurement procedures that ensure efficiency and value for taxpayers’ money. Any suggestion to the contrary is simply wrong.”
The two Salamanca executives listed as present have not responded to requests for comment.
*Listed at a table with Philip Hammond, who was defence secretary at the time of the event, is Kevin Lomax, who is chairman of two companies, one of which sells surveillance technology and the other, voice recognition-based security software.
Neither Mr Hammond, who was photographed outside the event, nor Mr Lomax would comment on their attendance at the party.
*The then planning minister Nick Boles was listed at the same table as a property developer who is a major donor and has been the subject of cash for access concerns in the past after acknowledging there is “20% truth” in accusations that political donations are made to buy influence.
Two directors of a property firm that specialises in retail development sat at the same table, according to the plan.
Mr Boles, the developer Mike Slade and the two executives did not respond to requests that they confirm their attendance.
