British Prime Minister Boris Johnson put no pressure on his Indian counterpart Narendra Modi over New Delhi's position on Russia's invasion of Ukraine when they met on Friday, India's foreign secretary told reporters.

India has not explicitly condemned the invasion by Russia, its biggest supplier of military hardware.

"They did discuss the Ukraine issue but there was no pressure," Harsh Vardhan Shringla said after the premiers met in New Delhi.

"Prime Minister Johnson shared his perspective on it, Prime Minister Modi shared ours - which is that the Russia-Ukraine war should end immediately. There was no pressure of any kind."

In their wide-ranging talks, Modi and Johnson vowed to give fresh momentum to overall ties and reviewed the progress made in the implementation of the Roadmap 2030 that listed ambitious targets for deeper collaborations in diverse sectors.

In his media statement, Modi said good progress has been made in negotiations for the India-UK free trade agreement.

"We have decided to do our best to conclude the free trade agreement by the end of this year," Modi said in presence of Johnson.

He said both sides emphasised on a free, open, inclusive and rules-based order in the Indo-Pacific while reiterating the need for respecting the territorial integrity and sovereignty of all countries.

"UK will work with India to boost security in the Indo-Pacific, including new fighter jet technology, helicopters and collaboration in the undersea battlespace. PM will also discuss new cooperation on clean and renewable energy," PM Johnson said.

We reiterated our support for peaceful, stable and secure Afghanistan, he said, adding it is necessary that Afghan territory is not used to spread terrorism in other countries.

On the Ukraine crisis, Modi emphasised dialogue and diplomacy to address the problem and called for an immediate ceasefire.

In his remarks, Johnson described the ties between India and Britain as "one of defining friendships of our times".

Today, we have agreed on a new and expanded defence and security partnership, he said.

Johnson said the UK is creating India specific open general export licensing to reduce delivery times for defence procurement.

We are telling our negotiators to get it done by Diwali in October, he said on the FTA.

"We aim to have a new Free Trade Agreement by Diwali...I have urged officials to get it done by Diwali. We appreciate the tariffs being dropped by India on certain goods and commodities and in return, we too are dropping some tariffs we levy. We also look forward to the close cooperation shared between the UK's NHS and India's health services," the British PM said.
