Indian Prime Minister Narendra Modi is to meet the Queen and speak in front of tens of thousands of people on the second day of his visit to the UK.
Mr Modi is to have lunch with the Queen at Buckingham Palace and then later give a speech at Wembley Stadium.
He will also meet business leaders. Deals worth £9bn between Indian and UK firms were unveiled on Thursday after talks with David Cameron.
Mr Modi’s three-day UK visit is the first by an Indian PM in a decade.
He has described India’s relationship with the UK as being of “immense importance”, while Prime Minister David Cameron has said the countries need to create “one of the leading global partnerships”.
But Mr Modi’s appearances have also attracted protest over allegations of religious persecution and a reduction in civil liberties since he came to power.
The businesses deals between the UK and India were announced after Mr Modi was hosted at Mr Cameron’s country residence Chequers.
