Gappy window - what can be done?

[mfarrow]

Hi

Our window in the back room is very gappy at the top. I've put in some foam at the top but it still gaps at the edges.

What can be done? The window looks square, but there doesn't seem to be a lot of overlap between the window and the frame.

As stated by God. Heel and toeing required.
As its externally beaded and over whet looks like a conservatory its going to be a fun job to do.
