Chancellor George Osborne and Foreign Secretary William Hague will set out to forge links with the new Indian government of prime minister Narendra Modi as they seek to strengthen Britain's trade with the powerhouse Asian economy.
The two Cabinet ministers are embarking on a two-day visit to India during which they will meet with key players in the administration in New Delhi - including Mr Modi - as well as leading business figures.
They are following in the footsteps of a series of foreign visitors - including the French foreign minister and the Russian deputy prime minister - who have arrived to pay court to the new premier since his landslide election victory in May.
