The new site cost £20m to develop and went live on Monday. It brings together all of the FCO's embassy and high commission sites onto the same platform, with the aim of presenting the FCO as a 'coherent worldwide online brand'.
The FCO's aim is for the new www.fco.gov.uk to become a key tool in the promotion of its four new policy goals - tackling climate change, terrorism and conflicts, and developing international systems. These goals are now being integrated into all of the FCO's work.
Outgoing FCO director of comms Lucian Hudson said: 'This puts the FCO at the forefront of web innovation in Whitehall, and ahead of other foreign ministries.'
The website is being led by the FCO's newly appointed head of digital engagement, Paul Bute, who was previously deputy ambassador in Katmandu. He has held a variety of policy and change management jobs since joining the FCO in 1994.
The new site has improved news content and includes dynamic elements such as interactive case studies supported by Google Maps, plus RSS news feeds and blogs.
