The wording is not as biased as you want to make us think.
I think the use of the term
her former study is non-neutral and will bias responses towards being against moving the portrait. Wording in polling matters and how a question is worded can markedly influence the outcome of the poll.
Do you really think that had the wording been:
"Was it acceptable or unacceptable for Keir Starmer to have Margaret Thatcher's portrait removed from his study in Downing Street?"
Or even (which would be more accurate):
"Was it acceptable or unacceptable for Keir Starmer to relocate Margaret Thatcher's portrait from his study to another location in Downing Street?"
That there would have been an identical response in the polling?
And the room in question is known as "The Thatcher Room", although that's not official.
Err ... so it isn't called the Thatcher room then.
The question seems perfectly appropriate to me given the room has deep associations with Margaret Thatcher, apparently.
It is a room in the workplace/home space that is Downing St. I image it has been used extensively, and therefore that it has deep associations, with every PM, not just, or even especially Thatcher.
