A deep dive into WHO report on Covid deaths in India and why govt opposes it

The WHO said it developed an ‘innovative’ and ‘robust’ methodology for its findings that are completely transparent. The Centre said all its letters seeking a clarification were met with a lukewarm response.
A raging controversy erupted over the Covid-19 deaths in India after a new WHO report.
What the WHO has said:

The global health body said it developed an ‘innovative’ and ‘robust’ methodology and availed a ‘completely transparent approach’ to gather data on the Covid deaths across the world. According to the WHO, the first two years of the Covid-19 pandemic caused 14.9 million (14,910,195 to be precise) deaths across the world between January 1, 2020, and December 31.

The officially reported global toll due to Covid-19 is 5.5 million, leaving us with 9.4 million excess mortality numbers that were unaccounted for.

A controversy has erupted over a World Health Organization (WHO) report, released a day ago, claiming that Covid-19 deaths in India were nearly 10 times the figures reported by the government, a statement vehemently rejected by the Centre.
