World Service staff bid farewell to iconic Bush House

The BBC World Service has been housed in Bush House since 1940.
By summer it will be empty as its 27 language services relocate to Broadcasting House in the West End of London.
To coincide with this week's 80th anniversary celebrations of the World Service, staff members past and present have been reminiscing about their time spent in the iconic building.
