Pomp and protests as Indian PM Modi visits UK

Current negotiations between the UK and India are a "huge moment for our two great nations", India's PM Narendra Modi has said on his visit to Britain.

Mr Modi and David Cameron are due to sign deals between Indian and UK firms worth more than £9bn.

His arrival in London was marked with a flypast by the RAF's aerobatic team, the Red Arrows, but there were also passionate protests.
