In the larger scale of things, not really - but more left than most were expecting, and arguably has drifted leftwards from where it was under the Tories. Leanings towards possible nationalisation of (aspects of?) rail travel and production of renewable power, and had made quite a few pro-employees-rights policies around wages, terms and conditions etc (in favour of the worker, not the company owner).
Obviously moving leftwards from "very right" is still "right".
