I'm hoping that both established political parties have had their day. They're rooted in some ideological / class struggle from the past, even though both have long abandoned their original positions and aimed for the centre with no particular aim in mind but to gain power.
People who vote for either one of them tend to do so on a purely tribal basis or because they're following some trendy media agenda.
The firebrand socialists are usually the product of public schools and privileged backgrounds ,whilst the keen conservatives often come from council estates and comprehensive schools.

At this point they like each other more than they like the British people , whom they see as unworthy thick peasants who's opinions and even votes don't deserve respect or consideration - we can see this in their actions and stances upon Brexit , but that's not the only issue over which they act as if they've been annointed to rule rather than elected .

In terms of the specific question here, Labour haven't got a clue where they stand because they have no conviction or belief other than how it effects their personal benefit - will leave or remain get them elected ?. That's all they care about, just as the other lot suddenly get committed to Brexit when the party of the same name threatens their seats.

Isn't it time people wised up to this crooked nonsense and demanded proper representation without party labels ?
