Just to clarify Fooby, Ed can request any evidence which holds relevance to what has happened, but the Police can (and almost certainly will) refuse the request. Until Ed agrees to proceed to trial they have no obligation to show their hand.
That being said, it quite often happens that the defendant chooses to go to trial, and the Police/CPS THEN drop the charges due to lack of evidence or otherwise. So you could get lucky.
Edit:
The following situations are also exempt from the Freedom of Information Act:
international relations, defence, national security or public safety;
the course of justice; (This one, in Ed's case)
intellectual property rights (trade marks, copyright etc);
the confidentiality of proceedings;
commercial confidentiality;
the interests of the supplier of the information, where supply was voluntary; or
the protection of the environment.
