Chicago Mayor Lori Lightfoot, the first Black woman and the first openly gay person to hold the position, has become the first incumbent in exactly 40 years to fail to secure re-election.
The Democrat, a former prosecutor elected in 2019 on a pledge to root out corruption, failed to secure sufficient support to reach a runoff scheduled for 4 April, with voters making clear their desire for change after Ms Lightfoot became dogged by her perceived failure to tackle crime in the Windy City.
