India-UK Comprehensive Strategic Partnership and the Vision 2035 Framework

India and the United Kingdom have a "Comprehensive Strategic Partnership". This is the highest label India gives to its closest partners. It means the two countries work together across almost every area: trade, defence, technology, climate, education and the movement of people. Since July 2025, the plan that guides this partnership is called India-UK Vision 2035.

Why does this partnership matter?

The UK is one of the world's largest economies and a permanent member of the United Nations Security Council. It is also a big financial centre: London is where many Indian companies raise money and where much global insurance and banking is done. For the UK, India is a fast-growing market of more than 1.4 billion people and a key partner in the Indo-Pacific region.

There is also a strong human bridge: about 1.8 million people in England and Wales described themselves as of Indian ethnicity in the 2021 Census, one of the largest ethnic minority groups in the UK.

Where did it come from?

The relationship has a difficult past, because Britain ruled India until 1947. After independence, ties were often cool, partly because of Cold War politics. Things changed step by step:

• 2004: India and the UK signed a Strategic Partnership.
• 4 May 2021: At a virtual summit, the two Prime Ministers raised the ties to a Comprehensive Strategic Partnership and adopted Roadmap 2030, a 10-year plan. They also launched an Enhanced Trade Partnership, aiming to more than double bilateral trade by 2030, and signed a Migration and Mobility Partnership.
• July 2024: The two sides launched the Technology Security Initiative (TSI), led by their National Security Advisers, for cooperation on telecoms, semiconductors, artificial intelligence, quantum technology, critical minerals and biotechnology.
• 24 July 2025: In London, the two Prime Ministers signed CETA and endorsed Vision 2035, which replaced Roadmap 2030 as the long-term plan.
• 15 July 2026: CETA and the Double Contribution Convention came into force.

How does Vision 2035 work?

Think of Vision 2035 as a ten-year family plan with five headings, where each heading has its own list of tasks. The five pillars are:

1. Growth and jobs: carry out CETA, refresh the Joint Economic and Trade Committee (JETCO), work towards a Bilateral Investment Treaty, and link capital markets, insurance and pensions.
2. Technology and innovation: build a UK-India research and innovation corridor, a joint centre for artificial intelligence, secure telecoms and joint work on 6G, and a joint guild on critical minerals, all linked to the TSI.
3. Defence and security: a 10-year Defence Industrial Roadmap, joint work on jet engine technology and electric propulsion for ships, more joint exercises, and a plan to make India a regional logistics hub for UK forces in the Indian Ocean.
4. Climate and clean energy: an Offshore Wind Taskforce, help for India's Carbon Credit Trading Scheme, civil nuclear cooperation including small modular reactors, and climate finance.
5. Education: an annual education ministers' dialogue, branch campuses of leading UK universities in India, and a Green Skills Partnership.

Who checks progress?

The two Prime Ministers give overall direction when they meet. India's External Affairs Minister and the UK Foreign Secretary review the plan every year. The first such review took place in June 2026. Separate ministerial dialogues handle trade, finance and technology. Vision 2035 sets no exact number targets for trade or investment; its time limit is the year 2035 itself.

The key facts and figures

• Trade: Total UK-India trade was about £47.2 billion in the four quarters to the end of June 2025, according to UK government data.
• Investment: At the end of 2024, the stock of UK investment in India was about £19.1 billion, and Indian investment in the UK was about £6.1 billion (UK government data).
• Defence exercises: Ajeya Warrior (army, held every two years; the eighth edition ended in Rajasthan in November 2025), Konkan (navy) and Indradhanush (air force).
• Mobility: The Young Professionals Scheme lets up to 3,000 young Indians and 3,000 young Britons (aged 18 to 30, with a degree or similar experience) live and work in each other's country for up to two years.
• Dialogues: Vision 2035 says the Foreign and Defence "2+2" dialogue will be raised to a higher level.

India's position

India sees the UK as a source of technology, capital and education, and as a partner for its own manufacturing goals. India has also pressed the UK on two long-standing concerns: the extradition of people wanted in India for economic crimes, and action against extremist groups operating from UK soil. The UK, for its part, has pushed for easier market access for whisky, cars and financial services, and for cooperation on irregular (illegal) migration.

Commonly confused concepts

• Strategic Partnership vs Comprehensive Strategic Partnership: A Strategic Partnership covers selected areas of close cooperation. A Comprehensive Strategic Partnership is a higher level that covers almost all areas. India-UK moved from the first (2004) to the second (2021).
• Roadmap 2030 vs Vision 2035: Roadmap 2030 (May 2021) was the first 10-year plan. Vision 2035 (July 2025) replaced it with five pillars and a longer horizon.
• CETA vs Bilateral Investment Treaty (BIT): CETA is about trade in goods and services. A BIT is a separate treaty to protect investors and their investments, for example by giving them a way to settle disputes. The two countries are still working on a new BIT.
• CETA vs CEPA: These are just names India uses for its free trade agreements. The India-UAE deal is a CEPA (Comprehensive Economic Partnership Agreement). The India-UK deal is called a CETA. Both are free trade agreements.
• Technology Security Initiative (UK) vs iCET/TRUST (US): The TSI is India's technology security framework with the UK. With the United States, India has a similar but separate framework (iCET, renamed TRUST in 2025).

Issues, criticism and the way forward

• Mobility and visas: Indian students and professionals have faced rising visa costs and stricter UK immigration rules. CETA does not include a general change in UK immigration rules, so this remains a point of friction.
• Carbon border tax: The UK plans a Carbon Border Adjustment Mechanism from January 2027, a tax on carbon-heavy imports like steel and aluminium. Indian exporters fear this could cancel some of the tariff gains from CETA.
• Extradition and security: Long-pending extradition requests and concerns about extremist groups abroad continue to test trust.
• Political change: The UK has seen frequent changes of Prime Minister in the last decade. A ten-year plan like Vision 2035 is meant to keep the relationship steady whoever is in office.
• Way forward: Experts suggest finishing the Bilateral Investment Treaty, using CETA's committees to fix problems for small exporters, building joint manufacturing in defence, and expanding education links so more Indian students can study at UK universities in India.

Concepts to Know

• Bilateral: Between two countries. A multilateral arrangement involves many countries.
• Tariff line: One specific product category in a country's customs list, each with its own import tax rate.
• Stock of FDI: The total value of all foreign direct investment built up in a country over the years, as opposed to the new investment that comes in during one year.
• Indo-Pacific: The large ocean region stretching from the east coast of Africa across the Indian Ocean to the western Pacific Ocean.
• Small modular reactor (SMR): A small nuclear power plant, built in parts in a factory and put together at the site. It is cheaper and quicker to build than a big reactor.
• Extradition: When one country hands over a person to another country to face trial or punishment there.
• Carbon Border Adjustment Mechanism (CBAM): A charge on imports based on how much carbon dioxide was released in making them, so that foreign producers face costs similar to local ones.
