No because Hughes is your real name and as such can be used by anyone without it being deemed offensive, ie Trump, May, Putin, etc, etc. and it can also be used in the workplace etc, ie "Hughes will deal with that" without it being offensive. //
I think we must agree to differ on this.
Hughes is my surname, it is not the name I am addressed by.
In forty-four years of full-time work, I was never addressed as 'Hughes' once, and I would have taken issue if I had been.
You say my surname can be used 'without offence' - that is clearly not true. I would be offended.
But returning to the OP, it has a lot to do with context, and intent.
The Right Honourable Lady in question is an MP, and the location is the Commons. The Home Secretary addressed her the way he did deliberatly, in order to be sarcastic and rude, that is quite clear to anyone who heard the exchange. He was called out on it by the Speaker, and apologised.
