Hundreds of politicians from Nato member states are to meet in Edinburgh, it has been announced.
The Nato Parliamentary Assembly holds its annual meeting in the city in 2009.
Around 600 politicians from the 26 countries making up Nato - the North Atlantic Treaty Organisation - will be in the city for five days.
The assembly acts as a forum to exchange views on the state of the alliance and issues such as nuclear policy, energy, security and economy.
Although there is no formal association between Nato and the assembly, there is a strong working relationship between the two bodies.
Edinburgh beat off competition from London, Cardiff, Manchester and Birmingham to host the conference.
The assembly meeting is expected to bring around £1m to Edinburgh's economy.
Nato was founded in 1949 to safeguard the freedom and security of its member states.
It is currently in charge of peacekeeping duties and security in Afghanistan.
