John McDonnell MP, Labour's Shadow Chancellor, said: "For too long, the West of England has been starved of the investment that is needed to create a fairer and more prosperous economy.
"The West of England will benefit with Lesley Mansell as their Metro Mayor as she will be a strong voice for the region and demand the resources from Government that are necessary to build more housing and to create the high-skilled, high-paid jobs of the future.
"There is immense potential for our economy in new technology and renewable energy in particular and I'm pleased Lesley has made this one of her campaign priorities."
Lesley Mansell, Labour’s West of England Mayor candidate, said: “It was good of John to join me on the campaign trail yesterday.
He shares my desire to tackle the inequalities of our housing market, the insecurity of our jobs market and to find green and creative solutions to our transport problems. The West of England needs a Labour Mayor to ensure no-one is left behind.”
