The NATO summit is expected to be one of the most important events in Welsh history with 60 world leaders descending on Newport for the two-day meeting.
Great organisation and manpower comes with arranging such an event of this scale. So who will be attending?

70 foreign ministers
70 defence ministers
28 NATO member countries
Over 2,000 journalists from the UK and international media organisations
An event of such prestige requires only the very best in fine dining and service. The Celtic Manor Resort has employed extra staff to ensure the delegates enjoy their visit to Wales and don't go hungry.

15,000 meals served to delegates and the media over two days
