From personal experience I would say that I have received a lot of pressure to breastfeed (currently 8 months pregnant), but I think it's largely down to the individual NHS trust and the individual midwives/health visitors etc.
As somebody who genuinely can't breastfeed, I do find it frustrating as when I politely tell midwives (when they ask why I'm not going to bf) that I won't be breastfeeding because I can't, they don't believe me and start saying that only a tiny percentage can't rather than won't. Well I am one of that tiny percentage and if they read my notes properly they'd know that. I have been asked if I will be bf at every single medical appointment I've had, well, not the ones with the consultant, but everytime I've seen a midwife, and it does get pretty frustrating. Then you get the "well you could express, or syringe feed colostrum..." No, I can't actually, read my notes, my breasts physically cannot produce milk or colostrum. 
The worst was a few weeks ago when I told one midwife I couldn't bf and she grabbed my boobs through my shirt and said in a very aggressive tone "you've got these haven't you?! What else do you think they're for?!"
As a survivor of sexual abuse I found this extremely invasive and inappropriate (and that's massively understating) and the thing that really annoyed me about it is that it's written in my notes that I've been abused (as some of the residual anatomical damage is relevant to pregnancy) and she had commented on it about five minutes previously!

DH and I complained to the hospital and it's all sorted now, and we received a profuse apology, but that's not the point. As luck would have it, I've had a lot of time to deal with my issues and so it just made me angry at the time rather than shook me up for weeks afterwards, but that might not have been the case with somebody else. Even if you haven't been abused, I can't imagine anyone would take well to that kind of thing.
Also, I do not believe that bf is always best. There are a lot of women out there with medical issues or on medication which mean that breastmilk would be very bad for their babies, and so in their cases, ff is the best thing. It's just not right or accurate to say that bf is always best. Yes, in an ideal world it is, but we don't live in an ideal world. The whole bf/ff debate seems to really polarise people and it just doesn't need to.
Everyone has their reasons for their choices and I think a bit of live and let live on both sides of the fence would go a long way. I think bf and ff alike get pressure and nastiness, and I genuinely don't understand why people don't mind their own damn business and let each mother make her own choice. Personally I don't give two hoots how anyone else feeds their baby
