Hi, I just left UK, the market is in as bad a shape as US, that is in any field right now. I was working with a university and have studied both in the US and UK. Britain is going through very hard times and it will take time for the economy to recover, so even if you get a job there is hardly anyone who maybe willing to sponsor you, hence you will not be allowed to stay there legally. Please check online UK border agency for further info, also in UK, many universities are cutting costs, down sizing, so unless you have something more than a PHD the probability of getting a teaching job is very small, they may consider you for an associate lecturer job, but they are not permanant and the university does not sponsor those jobs. Please invest yr time, money and energy wisely... my suggestion....you could study in the US and go for an exchange programs to UK/Scotland, Ireland) believe me the education is better in the US (in many universities in the UK professors are doing additional jobs and master students or their friends end up taking some of their classes, who are often not qualified to teach and do not know the subject well enough)
Best wishes... hope you did not mind my forthright answer..
