Wild flower ID

Wondered if you know what this pink flower is. I am assuming wild flower as it is at back of garden which backs onto woods and others plants in area are all woodland. It is covered in white and black insects at present so wondering if it would be better to remove

Forgot to mention the insects.

They are probably aphids, and personally I wouldn't bother about insects on wild plants because they'll be food for other wild stuff like ladybirds. But if they were close to my veg such as broad or runner beans, I'd give them a spray of soapy water.
