But here’s the comeback question: Which seems more likely – that our major parties will reform themselves and their way of doing things, or that a new party that people can understand the value of joining goes viral and grows its membership beyond that of the other parties?
Bear in mind that the Labour Party has just 150-160 thousand members, and the Tories have about the same. And the Lib-dems have about 60 thousand.
Also bear in mind that people are very dissatisfied with all our politicians, and with the way British politics operates.
Doesn’t it make you feel just a little bit ‘ambitious’ yourself?
