While Labour sent out the ballots for its leadership election in August, left-winger Jeremy Corbyn was the unlikely bookmakers' favourite to land the job.
With his rival candidates and large swathes of the press backing a call to vote for "ABC" - Anyone But Corbyn - the MP for Islington North, instead of resorting to personal attacks or abuse, attempted to set out his vision for the future of the party.
Now that he's been named as leader, perhaps it's worth revisiting Corbyn's vision for the future:
In an essay for the Fabian Society published in August, Corbyn explained that he wanted to give Labour's grassroots a greater say in the party's policies.
We cannot simply make policy at party conference once a year. We need to review our policy-making process to ensure that it is inclusive, accessible, participatory and able to take democratic decisions quickly when necessary.
Labour has drifted into a presidential model of politics in which the leader and their office comes up with all the policies. I want to change that.
A 'new kind of politics'
Corbyn also delivered a speech in Scotland on Friday where he will announce a 10-point policy plan as he promises "a new kind of politics".
This plan of the values and ideas I'm standing to deliver are intended to speak to all parts of Britain, not setting one against another as the Tories have done.
Combined, they are a new kind of politics: a fairer, kinder Britain based on innovation, decent jobs and decent public services.
However, moderate Labour MPs fear being purged from the party by a resurgent left-wing gathering around Mr Corbyn if he wins leadership.
Under Labour rules, MPs need approval from their local party to be re-selected to fight the next General Election. This is usually routine, but Labour has at least 100,000 new members who are entitled to vote for the first time in such elections and are believed to be overwhelmingly to the left of the existing membership.
Those on the right fear union figures around Mr Corbyn will use the process – along with the upcoming boundary review – to de-select MPs who are not “ideologically pure”.
