KIM Jong-un is to launch a Bachelor-style matchmaking contest to find a husband for his ‘spinster’ sister.

Unmarried Kim Yo-jong is North Korea’s most powerful woman after being elected to the hermit state’s powerful Central Committee this month aged just 29, reports The Sun.

Now big brother Kim, 33, is looking for a spouse for his sister and will personally vet 30 likely candidates from the capital Pyongyang’s elite.

The selection process is similar to the Bachelor show where women vie for the attentions of one man.

But in leader Kim’s version the stakes are far higher — with the hand in marriage of the sister of the dumpy despot the prize.

The regimen had tried to find her a man in 2012 but no one lived up to expectations and the process is now to begin again after she was moved into high office at the 7th congress, which was held for the first time in 36 years this month.

Candidates must be have graduated from or be students at Pyongyang’s Kim Il-sung University, be 5’10 in tall, good looking and have served in the army.

And a defector — who revealed the North Korean dating game, said Kim Yo-jong was a haughty woman with exacting standards.

The man — who escaped the hermit state by crossing into South Korea — said: “Students at Kim Il Sung University had to step aside to make way for Yo-jong in the hallway and no one was allowed to get in the same elevator with her except her classmates.

The defector added: “He chose 30 university graduates and students enrolled in master’s programs who served in the North Korean People’s Army. They were all members of the Workers’ Party, with outstanding appearance and height taller than 175 centimetres.”

There had been reports that she was married to the son of army chief Choe Ryong-hae but the defector, who worked for the North’s coal export business with China, said Choe’s son had actually died in a car accident in January 2013.
