"has Wes Streeting actually apologised to Rosie Duffield"
Not reported so I guess not.
"is he merely signalling an apology to potential Labour voters through the Guardian?"
That seems to be the intention but what he is actually signalling with his shit-weasel word salad is failure to admit, to take responsibility for and to apologise for his leading role in organising the witch hunt against women in the Labour Party.
""I was inundated with women in the Labour party, including parliamentary colleagues, who I do not consider to be shrinking violets, who were basically saying: ‘I’m really glad you said this about having a better conversation, because I felt afraid about voicing my concerns’. And I thought, if some of the strongest women I know are feeling silenced, we’ve got a problem.”
It's apparently a surprise and a mystery to Wes that some of the "strongest women" he knows are "feeling silenced".
Has he had a bang on the head and got amnesia?
Think Wes. Cast your mind back. Could it possibly be because you and Angela Rayner led a pitchfork-wielding rabble to hunt down women, accuse them of "transphobia" and expel them from the Labour Party?
How about the woman who was not even a member of the Labour Party who you terrorised?
No regret for teaming up with a vicious scam artist who has been accused by multiple women of sexual assault, who thought it was funny to prance around in a shell suit smoking a big cigar and, as if anyone could not get the reference, had a Twitter account with the fake URL "rape.com/savilles.apprentice" (sic) in the bio?
The PP in this thread saying, "You wanted an apology, you've got one and you're still not satisfied?" - there has been no apology.
All there has been is an acknowledgement that women suffered harm and a pusillanimous pretence that he had no part in causing that harm.
That's it. That is not an apology.
