Prime Minister Najib Abdul Razak may have a team to manage his Twitter account, but he still takes time to upload his own content.

"The Twitter account belongs to me. I have two methods: I tweet myself and I have a team (to do it for me).

"If it is a formal matter, my team will do it for me. If it is casual, my team will know because there might be typos.

"Usually (the casual tweets) are by me. (It may include) photos around the house, photos of the cat," quipped Najib.

Najib said this during a question and answer session at the One SSM Plus Carnival at Medan Mara, Kuala Lumpur today, after he was asked to reveal the identify of his Twitter account handler.

Apart from tweeting, Najib said his limited free time was spent on family and exercising, which he does at least twice a week.

"I can't balance (work and leisure) today, but I will find time to exercise and work out at the gym. I have a trainer who 'tortures' me for an hour," he said.

Najib revealed that when he works out on his own it would not be as intense.

"I have to admit that normally, I have two session with the trainer (a week) and the rest of the time I will exercise alone. But when I'm a lone, I do 'cheat' a little bit," he said while laughing.

On whether he had made online purchases before, the premier said: "Yes. I bought songs online."

"Some were classics and others were contemporary, such as Bruno Mars. I don't have to reveal what sort of songs I listen to or you will know which era I'm from."
