On the first day of Indian Prime Minister Narendra Modi's visit to Britain, his arrival was overshadowed by protests over a perceived rise in intolerance in India.
Narendra Modi has become the first Indian prime minister to visit the United Kingdom in almost a decade.
Mr Modi arrived in London for a three-day visit as the guest of British Prime Minister David Cameron.
Mr Cameron says British and Indian companies are announcing new collaborations together worth more than (AU)$13 billion.
"During this visit British and Indian companies are announcing new collaborations together worth more than nine billion pounds, but I think there is scope to go much further."
Mr Cameron says Britain wants to support Mr Modi in his efforts to transform India with improved infrastructure and education.
"We want to become your number one partner for securing the finance needed for this ambitious plan, making London the world's centre for offshore rupee trading. We are getting that started with plans already in place today to issue over one billion pounds of bonds right here in London, including the first-ever government backed rupee denominated bond to be issued internationally."
Mr Modi addressed the British parliament.
"So much of the moral history of India is linked to this building. So much history looms across our relationship. There are others who have spoken forcefully on the debts and dues of history. I will only say that many freedom fighters of India found their calling in the institutions of Britain."
He said the two countries have a chance to become one of the leading global partnerships.
"This is a huge moment for our two great nations so we must seize our opportunities, remove obstacles to cooperation, instill full confidence in our relations, and remain sensitive to each other's interests. In doing so, we will transform our strategic partnership, and we will make this relationship count as one of the leading global partnerships."
British Trade Minister Francis Maude says Britain has signed six deals with India, including a (AU)$1.97 billion investment by Vodafone.
Meanwhile, hundreds of protesters gathered at Number 10 Downing Street.
A number of different groups took part, including Sikhs, Muslims, Nepalese, Tamils and women's rights organisations, all citing concerns over growing intolerance in India under Mr Modi's rule.
The crowd chanted slogans and accused the Indian prime minister of human rights abuses.
Protester Bigyan Brasai criticised the UK for rolling out the red carpet for Mr Modi.
"The UK should not only look into the political and commercial aspects. The UK has a rich pride and culture of raising a voice for the voiceless countries and peoples, and instead it is the glory of the British values and culture, there is disrespect. They should keep pressure, that you (Modi), what you are doing is wrong."
Nepalese protester Kapil Rijal said Mr Cameron should raise human rights issues with Mr Modi.
"UK is a country of democracy. We can voice ourselves here and I hope David Cameron is going to do something and talk about these issues.There is nothing that can't be solved with diplomacy, but we need something to be (done). We need a diplomacy talk going on."
