As Prime Minister Theresa May finally dropped her grey suit and donned a sari on the final day of her visit to India, she declared the trade mission a success in her drive to build "global Britain".

During a visit that covered trade, IT, terrorism, visas, students and even India's self-appointed The King of God Times Vijay Mallya (hiding in England and wanted for questioning over millions in unpaid loans) there is now a little more clarity as to what each country wants from the other if Britain and India really are to meet on equal terms as trading partners.

As such, India has enjoyed having the full and undivided attention of Britain's leaders and we are now better informed on what India is working towards as we approach 2019 and Article 50.

And while all the talk still revolves around the gargantuan unknown, Brexit, India's priorities have now arrived on the agenda, fully-formed and reasonable.

Nuclear India

India has been trying for a number of years to gain entry into the exclusive Nuclear Suppliers Group (NSG). In short, this is the exclusive group of nuclear supplier countries that seek to prevent nuclear war by being at the table when the big decisions are made about the buying and selling of the technology and weaponry.

So far just about every world leader from Obama to Putin has endorsed India's entry but after a number of vetoes from China, their application appears to be in deadlock.

China, it would appear, seems keen to curtail India's development as the second power in the region and its blocking of India's NSG entry is one way in which this policy is currently playing out.

However, this issue has become one of national interest for India, and it will resurface as Modi approaches the next general election (also in 2019). India wants to know that Britain has its back for NSG entry as greater backing from another influential voice could help further India's cause and break the deadlock.

Terror

India has for a long time felt alone in its own fight against terror. After bloody partition and a number of wars against Pakistan there remains the feeling that the global community tends to view terror attacks, like Mumbai 2008, as a part of a continuum of domestic communal violence, and not a part of the current cycle of Islamic Jihadi terror.

It was long been a sore point that the Mumbai terror attacks are not given the same gravity as Paris, Brussels, London and New York - 9/11.

Britain will need to be careful here but India clearly wants global support from those fighting terror when its troops are attacked and its people are killed.

Visas for India's brightest and best

Quite rightly India wants better terms for its leading business men and top students to study and start their careers in England.

It is currently easier and cheaper for Chinese students to study in England and at £35,000 minimum salary for a working visa, India feels that it is not currently being treated particularly well.

Britain can do better on this, and despite claims that the UK is closing its door on EU migration and opening the doors to India, expect these terms to improve.

Information Technology and FinTech

India is mighty proud of its IT sector.

There was little surprise that May finished her visit to India in Bangalore, India's IT capital.

And firms like Infosys and its sci-fi campus is very much the India that Indians would like the world to see.

India and Britain are actually natural bed-fellows when it comes to IT, and especially the big-money branch of IT used in the financial services.

Boris, during his tenure as Mayor of London, was never shy to champion the Capital as the world's hub for FinTech and India and the UK, blessed by English as the lingua franca, could form a formidable tag-team against US hegemony in the sector.

Send back our bad boys

India wants its suspected criminals to be sent back for questioning.

There has developed something of a culture for those accused of high-level corruption and tax avoidance in India to find a comfortable and stress-free home under the protection of her Majesty rather liberal extradition laws.

Liquor baron and King of Good Times Vijay Mallya should be expecting a knock on his door.

What we don't know...

At this point the very idea of Britain and India arriving at a free trade agreement is hypothetical to the point of appearing like being a mere daydream during a political process otherwise filled with tedium and deadlock.

A huge question remains as to whether either May or Modi will be in power in 2019 when the Article 50 button is pushed.

The Indian general election - the largest and most chaotic in the world - in set for 2019 and Theresa May will almost certainly have to face an election on the terms of a parliamentary vote on Brexit.

Then comes the dreaded W word.

War.

Back in December 2015, India Prime Minister Modi went for afternoon tea with Pakistan PM Sharif. All seemed well. The fears that Modi and his right-wing RSS backers would take a tough line with Muslims home and abroad seemed, at that point, unfounded.

Nine months later and tensions have again escalated - after the death of Kashmiri militant (and social media star) Burhan Wani - India and Pakistan have retreated to the old playbook of accusation and counter-accusation.

Pakistan seems keen to leverage the Kashmiri crisis to its advantage.

In short, the Kashmiri people consider themselves about as Indian as an Irish man in 1984 considered himself British.

However, India considers Kashmir a part of its sovereign territory. A territory that has been fought for at great human cost, and one that will be fiercely defended.

The bad news for India is that conflicts of national identity really only go one way.

The Kashmiri people simply do not consider themselves to be Indian and the continued unrest in Srinagar - the images of children losing their eyes to Indian Security Force pellet guns, the burnt schools, the grieving women - could lead to a war that India would win militarily, but lose in the global media PR battle.

Modi, already carrying the burden of the 2002 Gujarat 'Massacre' where thousands of Muslims (officially 750, unofficially 2500) died, should be wary that nothing would derail a free trade agreement with Britain quite like the global condemnation that usually follows military aggression.

Theresa's final day in India

By PA

British PM Theresa May wore the traditional Indian clothing as she visited the Sri Someshwara Hindu temple in Bangalore, the southern city which has become the IT sector hub of the sub-continent.

The PM went to India at the head of a 33-strong business delegation with the aim of bringing down barriers to commerce and paving the way for a free trade agreement following Brexit.

Speaking to Sky News at the end of her three-day visit, she said: "Leaving the EU presents us with a world of opportunities and I'm determined to seize them.

"That's why I'm here in India, delivering on global Britain. And I have to say the response has been very good.

"During this visit, we've seen £1 billion worth of deals being signed and we've come to an agreement with the Indian government that we will work together with them on developing our trade relationship for the future.

"What does that mean? It means more jobs, more investment in the UK, more trade for British businesses and that's good for everyone."

The first leg of Mrs May's visit, in the capital, New Delhi, was dominated by tensions over visas, with Indian PM Narendra Modi putting pressure on the UK to ease restrictions on students and skilled workers coming to Britain.

Mrs May announced new measures to make trips to the UK easier for senior business executives

Mrs May announced new measures to make trips to the UK easier for senior business executives, and she offered to discuss improvements in the visa application process for Indian citizens in return for greater co-operation over the return of migrants who overstay their permission to remain.

But for the Prime Minister, trade has been the priority, with deals sealed during the trip expected to create more than 1,300 jobs in the UK.

Mrs May issued a warning on Monday of the risks of stagnation and falling incomes if the UK fails to make a determined push for new trade opportunities after Brexit.

"As Britain leaves the EU, we're determined not to turn our backs on the world but to forge a new, global, outward-looking role for ourselves," she told a business summit in New Delhi.

"Because we know from history what happens when countries do not embrace the opportunities of the world - they stagnate, they get poorer, they don't protect their people, they make them worse off."

Mrs May said she had detected real interest in India in doing more trade with Britain after its departure from the EU, which she aims to complete by 2019.

She told ITV News: "The message I've had here is that people actively want to do business with the UK."

"The message I'm getting is that everybody wants to build on the trade relationship that the UK has with India. They see opportunities and benefits for India and the UK going forward."

Although EU rules block the UK from entering formal negotiations on a free trade deal with India until withdrawal is complete, Mrs May has made clear she is determined to do the groundwork for an early post-Brexit agreement and to tackle barriers to trade which can be dealt with immediately.

Her trip has seen memorandums of understanding signed on intellectual property rights and the ease of doing business in India, and she and Mr Modi agreed to co-operate on cyber-security and tackling violent extremism online.

In Bangalore, she visited a Dynamatic Technologies factory where Indian workers assemble components machined in the company's Swindon and Bristol facilities for Airbus jets.

And she joined flag-waving children at the city's Stonehill Primary School to witness a flypast of Indian Air Force jets and helicopters in her honour.

The flypast was the first of its kind offered to a visiting head of government, and follows a similar display by the Red Arrows during Mr Modi's visit to the UK last year.

The Prime Minister had a garland of flowers placed around her neck as she arrived at the temple to the sound of musicians playing drums and horns.

The visit ended with Mrs May taking part in a Hindu blessing, drawing her hands together across the top of a candle flame and touching her eyes, in a traditional ritual. She was then given red powder to dab a single spot on her forehead.

She later welcomed plans for the Science Museum in London to host a season of exhibitions and events dedicated to Indian innovation next year as part of the UK-India Year of Culture 2017-18.
