Duggar clan may lose reality TV show after eldest son admits he molested his younger sisters
Celebrity Christian family scrutinised after son admits he molested sisters
In the realm of US reality television, the Duggars have stood out as the champions of old-school Christian values - until now.
The future of their TLC cable series is in question after the clan's oldest son Josh Duggar confirmed reports that, as a teenager, he had molested several young girls, including his sisters.
Online petitions and bloggers are calling for the show to be cancelled, after TLC announced on Friday that it had ceased reruns of past series.
The show has been telecast since September 2008 and, judging from the Duggars' various social media accounts, new episodes were in production last week when Josh Duggar's past caught up with him.
"We are deeply saddened and troubled by this heartbreaking situation, and our thoughts and prayers are with the family and victims at this difficult time," said TLC in a statement.
Duggar, 28, abruptly quit his Washington job as a lobbyist for the Family Research Council, which campaigns against abortion and same-sex marriage.
Online, he acknowledged molesting five female teens - including some of his nine sisters - albeit long before came into being.
"As a young teenager I acted inexcusably for which I am extremely sorry and deeply regret," Duggar said. "I hurt others, including my family and close friends. I confessed this to my parents who took several steps to help me address the situation."
His parents, Jim Bob and Michelle Duggar, devout fundamentalist Baptists, said it had been one of the family's toughest moments.

Jim Bob and Michelle Duggar, their children - the youngest is five years old - and grandchildren are household names among social conservatives and celebrities at right-wing parades and conventions.
Springing to Josh Duggar's defence has been Republican presidential hopeful Mike Huckabee, who said the fact that Duggar had acknowledged wrongdoing, sought help and moved on was "testament to his family's authenticity and humility".
The family has been in the line of fire before, raising hackles last year with remarks that were deemed to be anti-gay - and prompting calls for TLC to ditch the show.
On her Twitter feed, entertainer Bette Midler couldn't help but find "delicious" irony in Josh Duggar resigning from "an anti-gay 'family' group due to molestation allegations". News blog Gawker recalled how Jim Bob Duggar, an unsuccessful Senate candidate in 2002, once described rape and incest as crimes worthy of the death penalty.
