Chiswick, Notting Hill and Greenwich may strike many as some of the loveliest parts of London - but not Saul Sadka.

The scholar has sparked a huge debate with a viral post highlighting the 'London banana' of the best areas to live, while simultaneously decrying swathes of the city outside of the zone as 'horrible'.

Mr Sadka took to social media last week to post a map of the city with a hand drawn banana shape on top, writing: 'This is the London Banana. As long as you stay within the Banana, you'll have a great time in London.

'Almost everything outside the Banana is horrible these days, best avoid. Not clear why, or when this happened. But it is what it is.'

The post has caused furious conversation online as famously proud Londoners defend their local area, while banana dwellers smugly send the map to friends, family and colleagues.
