Trump Kim summit: Who's pulling the strings? Image copyright BBC/DaviesSurya On Tuesday, the world's attention will be fixed on the historic meeting between Donald Trump and Kim Jong-un.
There have been months of diplomatic gyrations leading up to this point, and there are four leaders who could plausibly claim some credit for making this once unimaginable summit possible.
But which of them has really directed this piece of political theatre? Here are four scenarios.
Kim Jong-un: master puppeteer The North Korean leader wants to achieve what his father and grandfather never could - a meeting with the US president which would, in his eyes, cement his legitimacy. But what will also secure his legacy is the economic development his country desperately needs and Mr Kim has his eye on that prize too.
To achieve this long-held desire he has dramatically shifted in character from isolated angry strongman to international statesman.
After months of fiery rhetoric and steady nucle..
It's the world's longest non-stop flight... for now Image copyright Airbus Image caption Singapore Airlines' A350-900 ULR (ultra long range), taking off on its first test flight Move over Qatar, and back off Qantas. Singapore Airlines (SIA) is reclaiming the world's longest non-stop flight.
From October, passengers will be able to fly from Singapore to Newark, New Jersey - a journey that will take nearly 19 hours.
The longest non-stop flight available at the moment is Qatar's 17.5-hour Auckland to Doha route.
That's closely followed by Qantas' 17-hour non-stop flight between Perth and London, which launched earlier this year.
But reclaiming the world's longest route is a bittersweet victory for Singapore's national carrier.
From 2004 to 2013, it offered the same non-stop service, from Singapore's Changi airport to Newark's international airport, which services New York City.

Could an emoji save your life? Image copyright Getty Images Emoji might not be your first line of communication in a disaster...
But researchers feel they could make a difference during emergencies like earthquakes, where every second counts.
Now, an international group of scientists are lobbying for an earthquake emoji to be added to the Unicode set - the standard group of icons available on digital devices worldwide.
But can one emoji really make a difference in a crisis?
Emoji-quake"Maybe up to one third of the world's population might be exposed to some [seismological] hazard," explains University of Southampton seismologist Dr Stephen Hicks, a founder of the Emoji-quake campaign.
"So we really want to be able to communicate to all of those regions, all of those different languages, and an emoji is an amazing way of doing that."

Police told BBC Hindi the discovery was "a breakthrough", but are yet to arrest the main accused in both cases.
Ms Lankesh and Malleshappa Kalburgi were both shot dead outside their homes in the southern state of Karnataka.

The high-profile academic was shot dead a year after he made remarks against idol worship, which had angered Hindu right-wing groups. Ms Lankesh, too, was a trenchan..

According to the People's Daily newspaper, an old rural house was scheduled to be demolished by 5 June in the town of Zhuyuan, eastern Zhejiang province, because its location was deemed to be high risk for geological disasters.

Xinhua says that the demolition team reached out to the local Zhejiang Wild Bir..
