Hunter Biden became so addicted to illicit sexual thrills that he once spent $11,400 on a single night of debauchery at a New York strip club and shelled out more than $21,000 to one adult 'live cam' porn website.

The scale of the descent of Joe Biden's son into a morass of drugs, drink and sleaze – leaving him open to possible blackmail attempts – is laid bare in hundreds of documents and photographs on his abandoned laptop.

The 50-year-old spent a fortune on escorts and ran up massive hotel bills, often paying for multiple rooms in a single night.
