How can I work out the percentage of different raster parcels in a polygon

I have a raster layer (LCM2007) that contains 24 classes of landcover and a shapefile, polygon, which represents areas in a survey.

I want the area, or percentage, of each class in each area.

For instance, I need to add 24 columns to the area shapefile (i.e one column for each class) and calculate the area of that class in the appropriate area...

Does anyone know how I can solve this?

I may be missing something but I have tried converting both to raster and combining but this didnt seem to give me the area of each land class per area. I have also tried clipping the raster file but don't know how to get the information I need from each clipped section. I have also tried using zonal tools (but have never used them before so may have done something wrong) and they didn't seem to work either.

I have about 1,600 different areas I need to do this for so a technique that would allow me to do all at once easily would be greatly appreciated! Thanks!
