PM Narendra Modi meets UK Prime Minister Theresa May in Hangzhou, China.

The meeting comes even as Theresa May has been under pressure at the G20 summit over Britain's trade links with the US and other countries after it leaves the European Union.

President Obama said the US would prioritise trade negotiations with the EU and Pacific nations over a UK deal.

Japan has warned of "drastic changes" after Brexit and said the potentially "harmful effects" must be minimised.

But May has insisted that the UK can prosper outside the EU and become a "global leader in free trade".
