DAVID Cameron has launched his party's manifesto for the coming election with promises of new rights to buy housing association homes, and money for brownfield development.

The "Northern Powerhouse" appears early on in the pledges, as the party promises to rebalance the economy with support for "metro mayors".

Construction of HS2, and the development of High Speed 3 to connect the north from east to west also feature; while a Brownfield Fund has been promised to open up land for development.

The homes plan also includes 200,000 "starter homes"and changes to the law to allow housing association tenants to buy their homes at a discount - in the same way as council tenants under Right to Buy.

Meanwhile, Green party leader Natalie Bennett has launched her party's manifesto called "For the Common Good" with promises to scrap Right to Buy, build 500,000 new social rented homes, scrap the Bedroom Tax, and reform tenancy laws.

They have also pledged to increase the minimum wage to £10 per hour by 2020.

Jonathan Tyler, the party's candidate for York Central, said: "For the Common Good spells out how the Green Party plans to end austerity and restore the public sector including local government service levels.

“The Green Party will reinvigorate public services, including renationalising the railways, restore high standards of health and social care, and develop a programme of renewable energy generation in collaboration with local communities.”
