North Korean men have been issued a mandate to cut their hair in the same style as leader Kim Jong Un, according to reports.

The Sun reported the dictator, who sports a ‘shaved at the sides and long at the top’ style, has demanded all men emulate his trademark look, also favoured by his late father and grandfather.

The cut is apparently known as the “ambitious style” in North Korea.

• ‘No plans for military increase’

According to the report, women have also been ordered to sport the signature ‘bob cut’ of the leader’s wife, Ri Sol-ju.

The mandates have allegedly caused a spike in revenue for hairdressers, who are struggling to keep up with the demand for those eager to avoid punishment.

The sweeping bouffant at the top of the head must not be longer than 2cm, while sides must be kept under 0.8cm.

It is believed government officials are patrolling the streets and forcibly cutting the hair of offenders on the spot.

Since his father Kim Jong Il’s death in 2011, Kim Jong Un has attempted to build his power base with a number of bizarre moves.

His defence minister Kim Chol was locked up for “insufficiently grieving” during his father’s funeral and his uncle executed in 2012 for dissent.

One year after his ascent, the dictator had a 550-metre message reading “Long Live General, the Shining Sun” carved into a hillside.
