Help needed with the name of a TV movie (UK)

Good evening,

I'm hoping someone can help me as unfortunately I only have a few memories to go by and Google isn't very helpful!

-(possibly) shown mid to late 1990s;
-(possibly) shown on BBC;
-one of the main characters was called 'Star';
-(possibly the mother) had tattoos, one of which I'm sure was a seahorse;
-character with tattoos would leave Star in the care of her sister a lot.

That's where the memories end! Hopefully someone can remember the name of the TV movie.

Thanks in advance,

Dan
