Leader of the opposition Jeremy Corbyn is hoping to set aside fractures within his own party in order to carve a different path for the U.K.
He will have a fight on his hands, however, to convince both dissidents within the Labour party and members of the public that he has the skills required to lead the government. Currently, the party holds 229 seats in the House of Commons, having suffered a painful defeat in the 2015 general election.
However, Corbyn has vowed to "overturn the rigged system" and return power from the establishment to the hands of the British people.
Like the Conservatives, Labour has pledged to enact the British democratic will and follow through with Brexit negotiations. But the party insists that its policies will extend far beyond this to focus on increased public spending and labour reforms.
"Theresa May will try to say that this is an election about Brexit while ignoring her government's failure and the issues that affect people's lives every day," Corbyn said, speaking in central London on his first day of campaigning.
The party, in its manifesto, has laid out aims to build a new "partnership" with the EU, including guaranteeing the existing rights of EU nationals and retaining benefits of the single market and customs union. Unlike the Conservatives, Labour has not made a commitment to reduce immigration numbers.
Elsewhere, Britain's national health service (NHS), which has long been central to Labour policies, will be one of several public services to receive extra funding. The NHS is set to receive more than £30 billion in extra funding, higher education tuition fees are to be scrapped and a new £10 ($12.88) an hour minimum living wage is to be introduced by 2020, according to the party.
He also intends to re-nationalize several public services, including water, railways and the Royal Mail.
Corbyn has proposed a £48.6 billion ($62.61 billion) tax plan to pay for his spending plan. This includes lowering the 45p tax threshold to all workers earning over £80,000, rather than £150,000. He also intends to introduce a new 50p tax for all those earning over £123,000 and raising corporation tax by more than a third to 26 percent by 2022.
The prime ministerial hopeful also seeks to win favor among the devolved governments of England, Ireland, Scotland and Wales by promising four additional bank holidays on each nation's patron saint day to "celebrate the national cultures of our proud nations." The pledge may well appeal to voters, not least because of the extra leave from work but also due to growing nationalist sentiment.
