Seven recent deaths in America have been linked to the use of electronic cigarettes. The federal government and some states have made moves to ban the use of the products. Other countries, such as India, are following. But some experts believe that vaping has a useful role to play in helping people to give up smoking.
So in this week's programme David Aaronovitch asks why have e-cigarettes become so popular, and what are the risks of using them?

The Perfect Storm: The United Kingdom, Brexit and its History
In a momentous week for British politics, David Aaronovitch presents a special hour-long edition of The Briefing Room in which he asks whether the United Kingdom's history might help us to understand better the political storms buffeting the country. What has the debate over Brexit done to Britain’s political parties and its parliamentary system, what does Brexit mean for the future of the union, what does it tell us about Britain’s place in the world and what has it revealed about the state of the country and the public’s faith in government as its provider and protector?

Has Narendra Modi changed India?
It's the world's biggest organised event: 900 million eligible voters across India have been to the polls in the last six weeks after five years of Narendra Modi's BJP government.
Narendra Modi's ambition was to project India as a global economic power, clamping down on corruption and burnishing its national security credentials. How far has he achieved this? And to what extent should India's non-Hindus be concerned about Narendra Modi's brand of Hindu nationalism?
David Aaronovitch speaks to experts to find out.

Could the United States and Iran go to war?
The British Foreign Secretary has warned of the danger of Iran and the United States stumbling into a war by accident. And the signs are ominous: the US accelerated the deployment of an aircraft carrier and B52 bombers to the Persian Gulf and all non-essential staff are being withdrawn from the US Embassy in Baghdad. US National Security Adviser John Bolton said any attack by Iran on America or its allies would be met with what he called unrelenting force. So what's the risk of a war breaking out?
