Kim Jong-un 'takes portable toilet to Singapore summit to stop his stools being spied on'

Secretive leader also believed to have brought his own food to historic meeting

Kim Jong-un's security precautions during his meeting with Donald Trump in Singapore reportedly include bringing his own personal portable toilet.

The North Korean dictator flew to the city-state along with two decoy planes and brought his own food with him for the historic summit, The Chosunilbo has reported.

Mr Kim's bullet-proof limousine has also been flown to Singapore, with one diplomatic source reportedly saying: "Tension was very high in North Korea, hence the secrecy."

The necessity for a personal portable toilet allegedly stems from Mr Kim's fear that foreign agents will look at his stools to gain an insight into his secretive life.

Rather than fly from Pyongyang to Singapore via Shanghai, which only takes six hours, the North Korean leader and his entourage flew the longer route via Beijing, as this requires less flight time over water, which is harder to protect.

Mr Kim's sister Kim Yo-jong reportedly flew to Singapore a few hours after her brother in his personal Soviet-era aircraft.

One of Mr Kim's personal (or decoy) planes was an Air China Boeing 747. A UN Security Council resolution forbids loaning ships, aircraft or crew to North Korea, however it is believed that China has secured approval from the US in order to transport the leader to the historic meeting.

While the North Korean leader's hopes for the meeting are unclear, Mr Trump is expected to push for the communist state to give up its nuclear weapons.

Last week the president promised to invite Mr Kim to the White House if the meeting goes well, saying he would expect the North Korean leader to look upon the offer "very favourably".
