The United Kingdom’s referendum on membership of the European Union in 2016 did not bring out the best in British politics. London poet Lallafa Jeltz, staunch socialist and proud Europhile, felt the urge to do something to stop the UK taking the stupidest decision ever. So it was that she took the fight to the social-media soapbox that was Twitter (now 'X') through the medium of a topical haiku a day. In the midst of the madness, the rabid arguments and debates, the poet wandered lonely as a clown. Years later, the dust has yet to settle. Brexit: A Haiku Diary is not just a collection of poetry, but also a succinct record and timely reminder of what was making press headlines at the time. Warning: contents may cause readers to despair at British politics all over again.
