The man behind Justin Welby

In the leafy seclusion of the Lambeth Palace grounds, Archbishop Justin Welby goes for his daily jog. He used to run along the Thames and over the bridges until Canon David Porter, his Chief of Staff, put a stop to it. David Porter grew up in Belfast in the 1960s and he knows how easy a target a lone high-profile jogger can be.

As well as being Welby’s physical protector, Canon Porter has taken on the role of his bureaucratic gatekeeper. ‘No one comes to Justin except through David’ — that’s the impression I get from everyone I’ve spoken to who has tried to contact the Archbishop recently. ‘Nothing happens without David’s knowledge and permission.’ If you’ve ever wondered why and when Lambeth Palace chooses to weigh in on political matters, remember the influence of Porter, a member of the Labour party. Think of the Archbishop’s most recent protest, against the proposed cuts in the foreign aid budget.
