I would
guess from Kate Hudson, who recently put out these books
and this
More clues:
Reconfiguring the European Left: Where do Britain and Ireland come into the picture?
Speakers: Kate Hudson and Andrew Burgin of Left Unity
Info:

Again a
total guess, but maybe either a policy to throw around at the forthcoming EU elections (though I doubt LU are putting forward MEPs), or in anticipation of the 2017 EU referendum? Or just in recognition of the resurgent left in europe and tying in whats in those books
