IF JEREMY Corbyn becomes the leader of the Labour party it will go down in history as the moment when corporate media began to lose control of the political narrative to social media.

The so-called fourth estate of British politics will have no option but to respond to the free flow of information and opinion in social media with editorial even-handedness, so their titles don’t become irrelevant and unread.

This development will instil in the public mind that when they have all the arguments and participatory democracy, they have real and unlimited power to change the consensus on civic circumstance.

Social media is becoming the Fifth (and perhaps ultimately dominant) Estate that will dramatically change the British political landscape.

It would be a bold politician who predicts the outcome of the next general election.
