Now, as the Democratic Party candidate, he is the frontrunner to win South Korea's election on 3 June.It's a dramatic reversal of fortunes for the 61-year-old, who at the time of Yoon's martial law declaration stood convicted of making false statements during his last presidential campaign in 2022.

Those charges still cast a long shadow over Lee, and could yet threaten his years-long pursuit of the top job. But they are also just the latest in a string of controversies that have dogged him throughout his political career.A rags-to-riches origin story combined with a bullish political style has made Lee into a divisive figure in South Korea."Lee Jae-myung's life has been full of ups and downs, and he often takes actions that stir controversy," Dr Lee Jun-han, professor of political science and international studies at Incheon National University, tells the BBC.

These actions typically include attempts at progressive reform – such as a pledge, made during his 2022 presidential campaign, to implement universal basic income scheme – which challenge the existing power structure and status quo in South Korea."Because of this, some people strongly support him, while others distrust or dislike him," Dr Lee says. "He is a highly controversial and unconventional figure – very much an outsider who has made a name for himself in a way that doesn't fit traditional Democratic Party norms."

"It's a wild roulette out there in AI world, you don't really know what you're getting."

"AI support can be a helpful first step, but it's not a substitute for professional care," agrees Mr Tench.And the public are largely unconvinced. A YouGov survey found just 12% of the public think AI chatbots would make a good therapist.
