Odd Jono - I must tell the East London Ramblers club next time they meet in Romford that they are in North London - they will be so entertained. Indeed the Havering Strategic Partnership, who describe themselves as East of the city bordering Essex, will no doubt have to comply with the new reality of Wikipedia. Most laughable will be the next time I meet up with some colleagues on this North London Borough - some of them are very protective of their geography.
Quiz question for anyone who is bored - how many other 'North London' boroughs have a Thames river frontage?
P.S. bonus points for anyone who can name, in order, all five most eastly London Boroughs?
