Access to GP response to PIP medical Inquiry

In general, do I have a right to ask my GP to provide a copy of his replies on the PIP medical information form?

Is a GP obliged to store his completed form in my medical notes?

My question is really outside of the Data Protection Act.

For instance, the time before my GP sent back the filled form to the DWP and didn't save a copy on my medical notes at all. My data rights don't arise if he does that because he doesn't hold the data, which is why I wonder if I'm entitiled to a copy before he sends any form back.

...but whether our daughter's GP kept a record or not, they were not wiling to tell me about it, even though I have daughter's authority to discuss/disclose. I found out roughly what they had put from the PA4 later - which was "too many questions to answer so not answering any" ! I did not mind or bother pushing it as his letter had got her a paper-based assessment, and after I wrote and took apart all the lies etc in the PA4 she got her Enhanced on both again.
