This page is about an active politician who is running for office, is in office and campaigning for re-election, or is involved in some current political conflict or controversy. Because of this, this article is at increased risk of biased editing, talk-page trolling, and simple vandalism.
"He was elected Labour Leader in 2015" - is "Labour Leader" a well-known term, or do we consider it a neologism for "Leader of the Labour Party"?
"He went to the North London Polytechnic without getting a degree." vs. "He went to the University of North London" and Alma mater value in infobox: I understand that there has been a change in the name of the educational institution, but can this be standardized in the article?
I have corrected minor errors in punctuation. Do note that punctuation should go before <ref> tags.
