Rich, is this noise happening when you're alone in the car or only when you have passengers?

only when parking, & on full lock.. ive checked the level & its ok...

Ot only makes the noise on full lock or it makes it the whole time you are parking or just when you are turning the wheel while parking?

not all the time, full lock & start up & parking speed... worst is full lock but it never did that before

had the belly panel off & had a lookie, everything seems ok except its squealing a lot more.. could it be the belt or the idler pulley??

does the belt look warn? I suspect you will have to take the belt off to check the idler pulley bearings unless there is better access than I remember to get a screwdriver / probe to it when the engine is running to listen to them.

belt was only changed 2 years ago /60000 km & looks in good condition....

I do all of mine annually when I give the cars a go over pre-MOT but 3700 miles doesn't seem like a lot for a belt. I have had problems previously with belt squeal after a coolant leak. I'm not sure what it did to the surface of the rubber, it looked fine but sounded dreadful.
If you have a long screwdriver try listening to each set of bearings you can get at but as you say the noise is worse on full lock, it is almost certainly the pump / rack, possibly contaminated fluid. when was the last time you changed it? does it smell burnt?

the water pump was leaking last year & was changed...new cam belt etc, the guy seemed to think the belts etc were ok..

had the mobile mechanic check it today, the idler pulley is knackered....
