The British political landscape fractures as Brexit approaches, what will fill the voids?

If the cracks now appearing in the unity of the two main British political parties turn into a chasm I wonder what will rush in to fill the void.  Now that moderate and Jewish MPs are abandoning the Labour party as it steers a course to the extreme left  under the leadership of Jeremy Corbyn and John McDonnell will others  amongst the more moderate  Labour MPs jump ship and join Chukka Umunna’s crew in “The Independent Group”?

Will the free marketers in the Conservative Party drag it to the right and allow unrestrained capitalism to run riot for the benefit of the rich and powerful at the expense of the less well off?

With the Greens and Liberal Democrats, according to the opinion polls, apparently unable to make progress there are several parties, some new and several long-established, which could step into the spaces created by Labour and Conservative fractious in-fighting.

The pro-Brexit SDP could revive with the assistance of politicians like prominent former UKIP member Patrick O’Flynn.  UKIP itself could make a comeback with Gerard Batten and possibly Tommy Robinson at the helm.  Anne Marie Waters and her For Britain Movement with its pro-Brexit and patriotic working-class stance could burst upon the scene.  Robin Tilbrook’s English Democrats could be of appeal to those supporting English nationhood and a parliament for England.

Meanwhile, the fissures in the British political landscape develop as Brexit approaches, but will the British Political Establishment connive to rescind the referendum result?  If it does, Nigel Farage and his Brexit Party are waiting in the wings to avenge such duplicity!
