The Scottish Greens, who are standing in the majority of Scotland's 59 seats, launched their manifesto two weeks ago with pledges of a £10 minimum wage for all ages by 2020, publicly-owned railways, opposition to the TTIP trade deal, and more powers for Scotland and local communities.
Membership of the Scottish Greens has surged to almost 9,000. One in ten members is ex-Labour.
Scottish Green MSP Alison Johnstone said:
"Greens across these islands are clear: we must end Westminster's failed austerity experiment. The Green Party's priorities mirror our own, and it would be great to have Scottish Green MPs working with colleagues on common causes such as the need to close tax loopholes, raise the minimum wage to £10 an hour by 2020, and return the railways to public hands.
"Here in Scotland there's a lot of admiration for Caroline Lucas and her positive and principled attitude. Electing more Green MPs like her would give local communities a fresh voice."
