No, no, no, no! It does vary from one health authority to the next. An abortion is legal in the UK up to 24 weeks, however if their is substantial risk to the women or the foetus there is no time limit. I believe late terminations of pregnancy, start with stopping the babies heart via an injection and then the woman is given drugs to induce a labour. Obviously this a very traumatic experience for the lady and would not be a decision that has been taken lightly, generally some sort of abnormality with the child or severe health problems to the lady. I do know of a girl who had an abortion at 20 weeks privately because she was 14, she had felt to scared to tell her dad and her mum had just died of cancer (when she was pregnant), so again things have to be taken case by case.
In Somerset you can have a termination up to 15 weeks. Then after, I think there has to be serious reasons for you needing to have one.
It is extremely rare that this would happen. Most health authorities impose a 12 - 16 week limit on these cases (where a mistake has been made with first step contraception and the baby is not wanted). I know that until very recently here you could not get your scan sexed because they feared that couples from cultures where it was favourable to have a boy not a girl would ask for abortions on these grounds.
I think we need to tackle the children in schools and get safe sex drummed into them. We have an 18 yr old lad at work who says he never uses a condom and it revolts me that he would put himself and his numerous conquests at such risk. As a child of the 80s (I am 27) we had safe sex drummed into us, i grew up terrified of HIV and unwanted pregnancy.
