Well this has ruined my evening.
Went to the loo and pulled the lever back and it wouldn't open. I noticed though that the lever only goes half way back also. I somehow got the cassette out (it didn't want to come out). Emptied it and tried to put it back in. It goes in but the blade is still shut and wont open inside the van. In the end all I could do was take the cassette out, remove the cover to the cassette, refit it and then manually slide the lever back inside the loo with my hands. So now the empty cassette is in and the blade is open but permanently. Obviously this is not ideal as even with the toilet lid down its going to smell but at least we can use it. Its pitch black so that will have to do until the morning but I'm hoping someone will have some pointers as to what we need to do to fix it.
There is definitely something wrong with the lever though as it only goes half way back and forward.
