It's an interesting observation, particularly for the fact that according to those charts UK's left party has been for the past decades a right-wing party, both on the economics and the liberal/authoritarian axes.
However, I'm not British and I've never followed the politics of any British party, nor my political views have changed substantially in the past few years, so I don't think my perception of the turn to the right of the Guardian in international politics might have been influenced by the shift in Labour's position.
