Probationary period and going for another job

[BimbaBirba]

I'm two weeks in a new job which I do not like and which has little to do with the job description. I'm not going to sue anyone for lots of reasons, not least because the only remedy would be compensation and being a very low paid job it just wouldn't be worth suing for.
So, I'm having to look around again! My previous employer has filled in my role already so I can't go back to my old job .
There is a job advertised that seems interesting but I'm not quite sure how to go about applying for it. Shall I explain that I'm only two weeks in a new job which is not working out? Shall I still put the current employer as a referee even though I've only been there for 5 minutes? Will it look really bad that I'm wanting out at such an early stage? This new employer requires references that cover the last 5 years of employment!
I'm also worried that if they seek a reference before I've been offered the job (at the short listing stage) my current employer will tell me to leave there and then. I can't really afford to be unemployed so I really need to play this well, I guess.
Any strategic advice greatly appreciated

I would give your former employer as a reference - current employer is unlikely to be able to say anything meaningful / that carries much weight given the short amount of time you've been there.

At interview you should be prepared to give a very credible explanation as to why you're leaving your current job after such a short amount of time. If I were the interviewer, I'd be concerned that you'd do the same if you didn't like the job in my company - be prepared to demonstrate that you aren't the sort of person that immediately gives up / walks away when things get tough.

You might also want to talk to your current employer about your job and see if anything can be done to improve things. No need to mention that you're thinking of leaving, but they may surprise you and be able to reshape the role.

Thanks for your advice. So would you put the former employer as a referee even thought the form clearly states that the current employer should be given as a referee?
I'm scared to talk about the fact the job doesn't match up to the description in case I'm fired there and then. My manager seems like the sort of person who would do that.
