The children of political scientist Robert Kelly, who became internet sensations when they gatecrashed his 2017 television interview, were back on BBC News with their father and mother Jung-a Kim on Thursday.

As Professor Kelly relayed his very serious views, Marion - wearing sunglasses and doing a funny walk-dance - toddled in and took a seat behind him.

Not to be outdone, baby James soon rolled into view in his stroller, swiftly followed by Kelly's very stressed and very mortified wife, Kim Jung-a, who quickly took the kids out of the room.
On Thursday, Marion and James were officially invited to sit in on the BBC News interview with their parents, as Professor Kelly discussed South Korea's response to Covid-19, and the challenges of working from home.
Of course, it was hard for the youngsters to keep still while their parents spoke about their struggle to keep them occupied indoors - and get some work done.
This is what happens when I sit down at my desk now to try to work. It is basically impossible for me to work now. Be kind to your employees with kids. After two weeks penned up in the house, those kids are gonna be climbing the walls. pic.twitter.com/KXquOrM7Lt— Robert E Kelly (@Robert_E_Kelly) March 16, 2020
"For us, as you can see, it's very difficult," said Kelly. "Employers who have employees with kids our age - it's very difficult.
"I'm getting two hours' work done a day, maybe three.
"They've got nothing to do, they're climbing the walls. It's really tough."
Kim said: "It's very difficult to stay in the house for a very long time.
"We try to go out and see the flowers and the trees and they can shout and scream."
