Deleting unwanted data from a sheet.

I am looking for a solution to remove any row without data in Column E of the attached file.
If an entry appears in column E then I require all data in that row kept.
It is a bit like sorting data by column E and if nothing in Column E, then delete entire row.
If a sort function can be undertaken, then sort by column A.
I have deleted data that usually appears in columns A and B for privacy.
