"80 military delegations from 46 countries" attended Farnborough according to the official website. While the individual countries aren't specified by Farnborough International, a list of delegations invited by the UK government has been obtained:
The military delegations are the focal point of arms trading activity. UKTI DSO invites delegations to attend as part of its arms promotion activities and schedules visits to the exhibition stands or business chalets of arms companies, and arranges meetings and receptions. The most senior UKTI DSO staff have programmes of meetings with delegations to put the case for UK weaponry.
Promoting arms to Libya
In 2010, a high profile was given to building links with the Libyan regime. Richard Paniguan, Head of UKTI DSO, met the Libyan delegation on the first trade day and Nigel Maddox, UKTI DSO's Senior Military Advisor, met or had lunch with the delegation on each of the remaining four trade days (FOI response 13.1.2011). General Obeidi, then Interior Minister and Commander of the Libyan Special Forces, who had requested "UK assistance on training his special police", met personally with both Gerald Howarth MP and the Duke of York (FOI response 27.1.2012).
In 2012, a Libyan military delegation was again invited, and attended.
Alongside private meetings, the organisers of Farnborough lay on other events for the military delegations. In 2010, a royal reception at St James's Palace was organised for the purposes of "high level relationship building with our overseas customers". It was hosted by the Duke of York and Ministers including Liam Fox, and the guest list included 50 Heads of Delegation and 25 CEOs and Chairmen of major arms companies including BAE, Lockheed Martin and Raytheon (FOI response 7.4.2011).
