Newport NATO Summit security challenge will be 'bigger than the Olympics' says police chief

Much of the summit will be held at the Celtic Manor resort in Newport

The officer in charge of policing the NATO Summit in Newport says the operation will be bigger than the London Olympics and the protection they'll need for the world's leaders is 'unprecedented in Britain'.

It's now less than a hundred days to go before it starts in September.

NATO, which stands for North Atlantic Treaty Organisation, was formed in 1949.

Its primary role is to protect the freedom and security of its 28 member countries, including the United Kingdom and America.

NATO summit meetings allow Heads of State and Government officials to make key political and military decisions, as well as building partnerships with non-NATO countries.

The summit held in Newport this September will be the 26th since the organisation was formed.
