Hugh Grant and Milly Dowler's parents are standing up against the invasive measures by which British tabloids get exclusive stories.

Grant first spoke about the issue when The Daily Mail ran a story about him and socialite Jemima Kahn in 2007; a story that he believes could only have been obtained through phone-hacking. In a similar incident, the parents of murdered schoolgirl Milly Dowler are also up in arms about the periodical News of the World's tampering of their daughter's phone.

The Dowlers' story is heartbreaking; employees from the paper allegedly erased some of Milly's voicemail and as such gave her parents false hopes as to her situation.

"And it went on to her voicemail. So I heard her voice, and it was just like I jumped, 'She's picked up her voicemails Bob, she's alive!''' Sally Dowler recounted the day she thought her daughter was still alive.

Grant's testimony focused on his disgust that such behaviour was allowed to be practised for so long. He said this obsession with other people's lives was sickening and everyone should stand up to fight the likes of it.

The 51-year-old actor also gave an account as to how and why he came to the conclusion that the tabloids were indeed overstepping their bounds and severely needed to back off. The publications, however, are standing their ground and saying that no such means have been used and tampering with potential criminal evidence was certainly not in their protocol.

Before the week is through, Lord Justice Brian Leveson will have heard testimonies from actress Sienna Miller, "Harry Potter" writer J.K. Rowling and Gerry McCann, father of missing girl Madeleine McCan.
