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?

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the deployment of an aircraft carrier and B52 bombers to the Persian Gulf and all non-essential staff are being withdrawn from the US Embassy in Baghdad.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?

Should vaccinations be compulsory?
With measles infections on the rise in the UK, should vaccinations be made compulsory?
Measles is an ‘entirely preventable’ disease, says the UN – and for a while the UK and other developed countries had prevented it.
But during the first three months of this year, the World Health Organisation reported 112,000 cases of measles. Over the same time last year it was 28,000
In the UK we once again have outbreaks of measles and a falling vaccination rate.
David Aaronovitch asks how much this matters and whether, as the Health Secretary has said recently, we should rule nothing out, even including compulsory vaccination.

Does the UK have an opioid problem?
Prescriptions for opioid painkillers have increased by 60 per cent in the UK during the last decade, and the number of codeine-related deaths in England and Wales has more than doubled.
The government is now planning to put prominent warnings about the dangers of addiction on the packaging of opioid medicines, to protect people from 'the darker side of painkillers' - as Secretary of State for Health Matt Hancock put it.
This is an effort to avoid the situation in the United States where 130 people die every day from opioid-related drug overdoses, which has prompted President Donald Trump to declare a national health emergency.
But are we really on the precipice of our own epidemic?
David Aaronovitch asks how the situation got so out of control in the USA and whether the UK should do more to regulate painkillers containing opioids.

What drives religious intolerance?
Is religious intolerance on the rise, and if so, what is behind it?
In Sri Lanka this week, people claiming to be acting out of religious belief killed more than 350 people, mostly of a different faith – in this case Christians.
Religious intolerance is a theme which has surfaced in the news with some frequency in recent years – be it the persecution of the Rohingya in Myanmar, the Yazidis in Iraq, the Uighurs in China or numerous blasphemy trials in Pakistan.
On this week's programme, David Aaronovitch asks whether religious intolerance – be it intolerance of religions, or by religions - is actually on the rise.
If so, who is leading this – governments? Nationalist political movements? Or the faithful themselves?
