THE Green Party pledged today to push Labour into “bolder” action on climate change and inequality as its four new MPs arrived at Westminster.

The party quadrupled its representation in the Commons at last week’s election, winning seats in Suffolk, Herefordshire and Bristol as well as retaining Brighton Pavilion.

Co-leaders Carla Denyer and Adrian Ramsay hugged on College Green, where they met today for the first time since their election victories, along with fellow new MPs Sian Berry and Ellie Chowns.

Ms Denyer described the moment as “history in the making” and said the Greens would be using their increased parliamentary presence to hold Labour’s feet to the fire on a range of issues.

She said: “With four times the representation in the House of Commons, we do hope and aim to influence the debate, whether that’s through motions, amendments, questions, work on committees and so on.

“And we’ll be pushing Labour to, especially in these first 100 days, take some swift actions on those low-hanging fruit that [it] could take to help make this country a fairer, greener place straight away.”

She cited scrapping the two-child benefit cap and revoking approval for the Rosebank oil field in the North Sea as two key aims for her party.

“My concern is that the Labour Party rolled back on a lot of its policies before they it got into power and so a lot of voters are concerned that it will continue to do so in government,” she added.

Mr Ramsay welcomed the new government’s decision to lift the de facto ban on onshore wind farms, but he said he wanted to see Labour do more, especially on home insulation.

“We will be pushing Labour to go further on things like climate, on things like the NHS,” he pledged.
