A new book claims Kim il-Sung (pictured), the father of Kim Jong-Il and grandfather of current North Korean dictator Kim Jong-un, ordered officials to shoot his son if he ever tried to reform the country

The founder of North Korea gave each member of his inner circle a silver-plated pistol and told them to murder his son if he ever tried to reform the country following his father's death.

A new book claims Kim il-Sung, the father of Kim Jong-il and grandfather of current North Korean dictator Kim Jong-un, ordered officials to shoot his successor if he ever tried to lead the country away from its Stalinist system.

Ra Jong-yil, the former head of South Korea's national intelligence service, claims he was told about Kim il-Sung's plan by a Pyongyang insider, who described how the inner circle were handed the guns and ordered to assasinate Kim Jong-il if he tried to change how the country is run.

Mr Ra told the Sunday Telegraph: 'Kim Il-sung had seen by the experiences of the Soviet Union what would happen if you start reforming or meddling with a dysfunctional system.

'The whole system inevitably collapses. He could not let that happen'.

Mr Ra's new book, The Path Taken by Jang Song-thack: A Rebellous Outsider, also claims Kim Jong-il wanted to end the hereditary system of rule which made Kim Jong-un his successor.

Instead, the book argues, he wanted the country to be ruled by a committee of 10, but because he died in 2011 before he could set the wheels in motion, his plans never came to fruition.

If they had the hermit nation could look very different today.

Mr Ra added: 'He said he most rational solution was a 10-strong leadership committee and for the Kim family to become the figurehead of the nation, a symbol and object of honour and respect but with no control over the day-to-day running of the country.'

The book is named after Mr Jang, the uncle who helped Kim Jong-un through the first months of his dictatorship after the death of his father.

Mr Jang was executed in December 2013 on charges including 'gnawing at the unity and cohesion of the party' and 'dreaming different dreams'.

Just two days ago MailOnline reported a UN investigator said Kim Jong-un and his dictatorial regime should face a crimes against humanity probe over 'Nazi-style atrocities' committed two years ago.

An investigation, commissioned in 2014 has concluded that North Korean security chiefs and possibly leader Kim Jong-un should face international justice for ordering systematic torture, starvation and killings.

Marzuki Darusman, the UN's special rapporteur on North Korea said: 'In addition to continuing political pressure to exhort the DPRK (Democratic People's Republic of Korea) to improve human rights, it is also now imperative to pursue criminal responsibility of the DPRK leadership.'

The 2014 report prompted the U.N. General Assembly to urge the UN Security Council to consider referring North Korea to the International Criminal Court for crimes against humanity.

Only the 15-member Security Council can refer the situation in North Korea to the ICC, but diplomats say China, North Korea's main benefactor, would likely veto such a move.

The book's revelations come as Kim Jong-un was spotted inspecting the Gold Cup athletes comprehensive food factory in Pyongyang.
