Cork City Council defends installation of 'robot trees'

Installation of the five high-tech CityTrees is under way at St Patrick Street and on the Grand Parade.
The city's Green Party councillors have welcomed the initiative, but critics accused the local authority of nothing more than 'green-washing' or misleading the public.
