Who can identify this?

I have a row of bushes and trees that I inherited when we moved house. Can anybody identify this one please? I'm not sure if I should prune it etc. Thanks

 

Catrin is it possible for close ups of the foliage please on this and your other threads as it makes it easier when trying to identify.

 

Looks like a bewildered tree, to me.

 

Hello, I have finally got some new pictures of my bushy tree. I hope you can see the picture, I've had problems uploading photos :/

 

Thanks for the picture. At first I thought it was Lilac but the leaves aren't set right for that and now I'm struggling. I recognise it but can't put a name to it, sorry! Perhaps other members can id it for you.
