Wasilla Bible Church publicised the event in Anchorage, Alaska, where Palin – dubbed the pit-bull terrier with lipstick – is governor.

The program is being run by the notorious fundamentalist Christian group Focus on the Family.

The group is supporting Palin’s run for the vice-presidency.

"You'll be encouraged by the power of God's love and His desire to transform the lives of those impacted by homosexuality," said the ad in the church's bulletin.

Governor Palin's nomination as Senator John McCain's running mate has been warmly endorsed by conservative Americans.

She opposes gay marriage, abortion, supports the teaching of intelligent design alongside evolution and denies climate change is happening.

She has attended services at Wasilla Bible Church for the past six years.

Her views on the so-called "ex-gay" movement, dismissed by medical authorities and scientists, are not known.
