Well, if anyone is still in doubt about Starmer's socialist credentials, he's blown them out of the water now by praising Thatcher. From the Sunday Telegraph (!) via the Guardian:

Keir Starmer has praised Margaret Thatcher for effecting “meaningful change” in Britain in an article directly appealing to Conservative voters to switch to Labour.

Writing in the Sunday Telegraph, the Labour leader said Thatcher had “set loose our natural entrepreneurialism” during her time as prime minister.

I can scarcely bring myself to say more. Except that I've been bloody telling you about him, haven't I?
