That's probably because the City of London isn't in any meaningful way whatsoever a "tax haven".
Fretting over the utter archaicness of the corporation, the power of the financial lobby and the connection of actual tax havens to the city doesn't make it a tax haven. Notice how the Monbiot piece is silly with irrelevant footnotes (in case you're worried he's pulling your finger on the date of the Lord Mayors parade, don't worry, it's carefully sourced) - except the bit where he makes his central assertions?
Here's the relevant test: Does incorporating inside the jurisdiction of the City of London change your tax liability compared with incorporating anywhere else in London, in any way whatsoever (except business rates, which are actually slightly higher in the city)?
