Euonymus ?

I've been trying to ID this shrub in my front garden.
It's evergreen, approx 3m high by 2m wide and is growing tightly against my pieris, (my Gran planted it there around 20 years ago after getting a shrub collection from Spaldings). It does need to be cut back a bit so I thought it would be best to ID it first so that I know when and how to prune it.
Looking both online and in my RHS plant books, it looks like it could be Euonymus myrianthus. I'm fairly sure it has yellow flowers in summer.

Here are some pictures of the leaves,

in advance

 

It is definitely not Euonymus myrianthus.
Don't think it is any Euonymus sp.
Euonymus flowers are tiny and very easy to miss.

I wonder if it is Ligustrum sp...common name Privet?

Thanks @Silver surfer
I'm can't remember if the flowers are the same as the ones in your links, so the only way to tell is to wait until it flowers. The leaves are the same though

 

It looks like the leaves of a Ligustrum but the flowers are white aren't they.

 

Yes...Privet flowers are white and smell horrid.

 

No they dont, they smell very nice.
Well I think they do anyway
