“Congratulations @BorisJohnson on assuming office as Prime Minister of the United Kingdom. I wish you success and look forward to working with you to further strengthen India – UK partnership in all spheres,” Modi tweeted.
The 55-year-old former foreign secretary and London Mayor laid out his vision as Prime Minister in his first speech on the steps of Downing Street after a meeting with Queen Elizabeth II at Buckingham Palace, during which the 93-year-old monarch formally invited him to form a government after accepting Theresa May's resignation a little earlier.
"We will restore trust in our democracy and we are going to fulfil the repeated promises of Parliament to the people and come out of the EU on October 31, no ifs or buts," Johnson said, adding that while he does have 99 days to that deadline, the country has had enough of waiting and the time to act on Brexit is right away.
A picture released by the palace showed Johnson shaking hands with the 93-year-old monarch and bowing.
Johnson, who has in the past described himself as a son-in-law of India by virtue of his now estranged wife Marina Wheeler's Indian mother - Dip Kaur, has stressed that the UK's relationship with India must run deeper than just trade.
In reference to India-UK relations, Johnson is on the record saying he wants to pursue a new trade deal and is expected to build on his self-confessed "personal relationship" with Prime Minister Narendra Modi to deliver a "truly special" bilateral relationship.
