Given the genuineness of your query I was tempted to respond by saying 'our work is done here'.
However, the network that came together under the Lexit campaign still exists in a number of forms.
1. The Political Education Project, has provided training for hundreds of working class activists. This directly emerged out of and by Lexit campaign supporters:
Political Education Project – Understanding the World in order to change it
2. A number of Groups formed at the time - in Manchester, the north of Ireland, the West Midlands and elsewhere have continued to meet and engage in variety of campaigns in workplaces and communities.
3. Most of the Lexit Network supporters were active in their own unions and organizations before the formation of Lexit and continue to be now. The Network was formed in recognition that it was vital that we leave the EU (and defeat attempts by Remainers to overturn the result). This was achieved. However, we also recognised that we do so on the basis that we seek to transform Britain in the process: a much longer term process and building on the central motivation driving the vote to leave the European Union - working class dissatisfaction with the present.
You'll no doubt be pleased to learn that the network of socialists, trade unionists, community activists and others that comprised the Network remains very much active.
Why do you ask?
