The Guardian journalist Seamus Milne hailed it as "a political eruption of historic proportions". The Prime Minister David Cameron claimed it represented a threat to Britain's national security. Whatever else it may achieve, Jeremy Corbyn's success in gaining the leadership of the Labour Party has certainly unleashed the surreal in British politics.
To understand more soberly what the left-wing maverick's overwhelming victory - and the humiliation of Labour's mainstream candidates - might mean, we need to first answer how Corbyn achieved his success. The key was the manner in which the post-war political system, which was built on the divide between social, democratic, and conservative parties, is now being dismantled. It is a process that can be seen not just in Britain, but throughout Europe.
The broad ideological divides that have characterised politics for much of the past
 two-hundred years have,over the last few decades, been largely erased. Politics 
have been reduced to a question of more technocratic management, rather than
 social transformation.

One way in which people have felt this change is through a crisis of political representation,
 with a growing sense of being denied a voice, and of political institutions being remote 
and corrupt. As mainstream parties have discarded both their ideological attachments
 and their long-established constituencies, the public has become increasingly 
disengaged from the political process. The gap between voters and the elite has 
alarmingly widened.

Voter disaffection
The main beneficiaries of this process have been right-wing, anti-immigration populist groups, such the National Front in France and Independence Party in Britain. But parties towards the left - like Syriza in Greece, Podemos in Spain, the Scottish National Party - have also been able to tap into that popular disaffection. Corbyn has done the same.
What makes Corbyn's success different, however, is that this is the first time that a mainstream social democratic party has become a vehicle to express disaffection with mainstream politics. This says as much about the state of the Labour Party as it does about Corbyn's ability to reach out beyond the mainstream.
Ever since the 1980s, the Labour Party has been hostage to reinvention. The triumph of Thatcherism, the neutering of trade union power, the rejection of old-style Keynesian politics, a greater acceptance of the market principle - all have helped deprive the party of both its social base and its raison d'etre.
After a decade of internal civil war, the party was reborn in the 1990s as the "New Labour", a media-savvy, technocratic, middle-ground party that had largely cut its links with the working class. It became, under the leadership of Tony Blair, a powerful machine to win elections. But it also became hollowed out as a living, breathing political party. In the decade after 1997, the Labour Party won three successive elections - but lost nearly a quarter-of-a-million members.
The combination of popular disaffection and an ideologically shallow Labour Party has provided Corbyn with his opportunity. But how will his success change the Labour Party and politics more generally?
Traditional Labour
Corbyn's supporters argue that his victory will help revitalise the democratic process, and give ordinary people a political voice that they have lacked. There is certainly something refreshing about Corbyn's willingness to talk of political values and principles, rather than merely repeat what might be electorally safe. Yet, what has been striking about Corbyn's first week as Labour's leader has been his unwillingness to reach out beyond his natural constituency. In all his speeches, Corbyn has addressed those who already support him, but not beyond. He has shunned the media and often refused to answer journalists' questions. Corbyn complains that the media is biased and wants only to demonise him. There is truth to that, but his dismissal of the media also shows a disregard - even contempt - for the wider audience and an unwillingness to be held to account.
Traditional Labour politics was less about building mass democratic movements than about looking to the state to act as a lever of social change. Corbyn follows in this tradition, which is why many of his policies are often deeply illiberal, for instance, the support for legal constraints on hateful and unacceptable speech and state regulation of the press.
Even where Corbyn has attempted to promote popular democracy, the results have not been particularly democratic. Much has been made of hisfirst appearance as Labour leader at the Prime Minister's Questions convention - a weekly ritual in the parliament, at which the prime minister faces questions from the leaders of the oppositions and other MPs. It is one of the few occasions at which the prime minister can be held publicly to account. Corbyn decided to crowdsource his questions. Cameron was able easily to answer questions from "Marie", "Claire", and others who had emailed Corbyn, but faced no interrogation from Corbyn himself. The result was not greater democracy, but less accountability and an abdication of leadership.
Corbyn's elevation to Labour leader is neither an historic shift nor a national threat. It is another expression of voter disenchantment. Labour's new leader has shown little evidence that he knows how to shape disaffection in a progressive fashion. The danger is that Corbyn's impact may be to fuel even greater disillusionment with the political process.
