Hey Shadow Minister,
(From an earlier comment to Paul1405)
"Finally, the reason that the BLP has swung so far to the left is not from the consensus of the party room, but because the leadership selection has been hijacked by left whinge activists. Given that the ALP has allowed selection of their leader by 50% contribution of the rank and file, who have already shown their more left whinge choices, there is a fair chance of this happening to the ALP."

Whilst this may be true I think its only one part of the story.
The other part of that story is the status quo of the voting public.
Is it a fair statement to say the left are constantly being bolstered with fresh troops, in the form of immigrants which are likely to firstly support the liberal left anti racism side of politics?
I can't see supporters of Islam as being in any way supportive of other other left leaning cases though.

AC,

Labour was soundly beaten in the last 2 elections precisely because they had veered to the left. Jeremy Corbyn would have been far more comfortable in the greens as a protest politician.
