the RHS seems less concerned about mites on apples [I have red felt gall mites on mine] as they rarely affect fruiting. Though mites are microscopic and these seem to be bigger. Any chance of a clearer photo?

welcome to GoY

Difficult to take clearer picture but they are very small reddy colour and you can see them moving about. The leaves seem quite sticky too

there appears to be aphids too and there are pinkish forms of that. aphids would explain the stickiness

either way they wont affect the fruit.
use a soapy water spray to get rid of the stickiness and greenflies.

Thank you for your help I will try using soapy water as you suggest
