Barry Gardiner has been appointed as the new Shadow Energy and Climate Change Secretary.
Labour Leader Jeremy Corbyn made the announcement after Lisa Nandy said she was resigning from her post yesterday.
Mr Gardiner served alongside Ms Nandy in the Shadow DECC team.
He was previously appointed to the front bench as Labour’s Shadow Minister for the Natural Environment and Fisheries in 2013.
Most recently Mr Gardiner was Ed Miliband’s Special Envoy for Climate Change and the Environment.
The news comes as a string of Mr Corbyn’s shadow cabinet have quit as he is facing a vote of no confidence from his party MPs.
