Scheme will offer training for plumbers, welders and carpenters as well as promoting trade union recognition

Plumbers, electricians and welders will be in huge demand as part of a national plan to train people for an extra 400,000 green jobs in the next five years, Ed Miliband has said.

The energy secretary unveiled a scheme to double the number of people working in green industries by 2030, with a particular focus on training those coming from fossil fuel jobs, school leavers, the unemployed, veterans and ex-offenders.
