Kim Jong-un now weighs a whopping 22 stone and has piled on the pounds since taking power, according to South Korean spies.

Despite his weight, the South's National Intelligence Service (NIS) said the North Korean tyrant is not displaying any “irregular symptoms”.

The People Power Party's Rep. Ha Tae-keung was briefed in a closed-door meeting about the 36-year-old dictator’s health.

Ha quoted the spy agency as reporting: "Kim currently weighs in the 140kg range after having gained an average of 6 to 7kg per year over the past eight years since weighing 90kg in August of 2012.”

The NIS did not consider his obesity a big issue due to his relatively young age, Yonhap reports.

However, he is not displaying any 'irregular symptoms'

Back in April, reports claimed that Kim had died or was in a vegetative state following supposedly botched heart surgery.

He did not make any public appearances for 20 days, fuelling the rumours.

However, North Korea released footage of Kim visiting a newly-opened fertiliser plant on May 1.

Meanwhile, the hermit kingdom convened a meeting of the Supreme People’s Assembly to introduce an anti-smoking law.

It adopted a Tobacco-Prohibition Law and Revising and Supplementing the Law on Enterprises, according to the official Korean Central News Agency.

Its report reads: "The law specifies places and units where smoking is forbidden, such as spaces for political and ideological education, public places including theatres and cinemas, and institutions for nursing and upbringing children, educational institutions, medical service establishments, commercial and public welfare service facilities, and public transport means.

In April there were rumours the leader had died, however, he was later pictured at a newly opened fertiliser plant

“It also indicates the contents of penalties for the behaviours of violating smoking rules, etc.”

North Korea has high rates of smoking, with 43.9% of the male population smokers as of 2013, according to the World Health Organisation.

Kim is known as a chain smoker who is frequently seen with a cigarette in hand in photographs in state media.

He was spotted taking a cigarette break at a railway station in the southern Chinese city of Nanning in 2019 on his way to Hanoi for his second summit with US president, Donald Trump.
