Hi Harry, your pics are definitely too small !! 

Yeh your pics are too small...but looking closely it seems more like a False smooth snake (Macroprotodon brevis). Although an enlarged photo could prove me wrong... 

I think so Matt ! 

These are thumbnail links - we've seen this before...

To see the real deal, remove "thumbs90/" from the links.

Amazing how good Matt's eyes are - Macroprotodon brevis, it is! 

Thanks for that guys. I had a couple of (what I was told were ) adult Southern Smooth snakes in the same area of the garden during winter of 2008. Perhaps they were wrongly ID'd perhaps they were False smooth snakes as well.I have attached a photo of it, what do you think?

Sorry for the small photos, I have now removed the "thumbs90" as Jeroen suggested and got an improved result size wise in the original query.
This morning I had a small snake, about 30cms, in a nectarine tree. Can you also ID it for me?
Once again many thanks for your help, asking is the only way to learn.

I'd say the last one is a Montpellier snake (Malpolon monspessulanus), those scales look quite like it. 

the 1st looks like Macroprotodon brevis to me, but the 2nd is definitely a Malpolon ;-) 

Same here
