South Korea's opposition leader has become the latest politician to publicly shave his head in a protest against the government.

Axar.az reports citing BBC that Hwang Kyo-Ahn had his hair entirely shaved off in front of supporters and journalists outside the presidential palace on Monday evening.

The protest is over a new justice minister, Cho Kuk, whose family is embroiled in corruption allegations.

Last week, two female MPs shaved their heads over the same controversy.

They want Mr. Cho to resign or be sacked by President Moon Jae-in.

Why shave the head?
South Korea has a long tradition of hair shaving as a form of protest.

The act is rooted in traditional Confucian teaching and has historically been seen as a way of demonstrating a commitment to a cause.

During the 1960s and 70s, when South Korea was under military dictatorship, dissidents would often shave their heads as a sign of resistance.

Over the past decades, activists and politicians have used it as a way to protest.
