Power steering fluid leak

[ffrenchie]

I've just noticed there is oil on the passenger mat in the car and it's clean and clear so the only thing I can think of is power steering fluid. I'll jack it up in the morning for a look but has anybody had this kind of thing before, give me a clue where to look ? I can manage without it but it is inconvenient and it's dark and raining now and after tomorrow everywhere will be shut for a few days. Ah well, gives me an excuse to be miserable over Christmas I suppose.
