Half of those responding to the latest Ipsos Mori poll said they held 'unfavourable' views of the Duke - compared to the near 70% who backed the Duke before the Sussexes' high-profile decision to step away as working royals in 2019.

It also emerged that less than a quarter of those polled (23%) said they planned to read his bombshell new memoirs - which has become the fastest selling non-fiction book ever after selling 750,000 copies in the UK.
