The lilac (pretty flower) doesn't look very old - you'll find it increases its flowering as it gets bigger.
If the gooey substance (its blurred in the pic) is orangey coloured, remove that stem immediately.

Prune your lilac as little as possible (and only immediately after flowering) to encourage flowering

Hi Bamboo, thanks for your reply, I will remove it now, only yesterday initially I noticed the gooey stuff was red, it was like the plant was bleeding and i have never seen this before and today when I checked it the goey stuff turned orange and is dripping down onto the new unopened foliage. do you have any ideas what it could be and why it happened?

It'll be bacterial canker - there's been a wound of some kind and its become infected. Hopefully its just that stem and hasn't spread to the rest of the plant.

Thanks bamboo, I have noticed that the gooey stuff has dropped down onto an unopened branch, its still yet to emerge will this one be ok or should I try to wipe it off with something as I cant cut this one off yet.

Provided there's no wounds or cracks or damage in the unfurling one, it should be okay - the bacteria can't enter sealed surfaces. The risk with wiping it off is that you may cause a little bit of damage through which it can enter...
