Diplomats and other government officials will intensify their efforts to achieve, as a source told the newspaper on Friday, "reckoning with the past," which will include the return of the famous Koh-i-Noor diamond alongside many other historical objects of Indian origin.
It can become the largest restitution claim that the UK has ever witnessed, according to the report.
Talks on the reclamation of artifacts are expected to begin later this year, and they may influence relations between London and New Delhi in other areas, such as trade, the news outlet said.
The Koh-i-Noor diamond is one of the world’s largest cut diamonds, weighing 21.12 grams (about 0.7 ounce.) In mid-19th century, it was taken to London and became part of the Crown Jewels of the United Kingdom.
