Keep Britain Tidy has launched Soapland Litter Watch, and is appealing to viewers to report sightings of litter being dropped on the main soaps.
The charity also plans to contact the programmes’ script teams and ask them to show the characters being reprimanded or fined for their actions.
EastEnders’ Dot Branning and Coronation Street’s Becky McDonald have been the subject of complaints from campaigners in the past for dropping their cigarette ends on the floor.
Fans have been asked to report incidents of littering in the soaps via Facebook or Twitter, and to carry out surveillance between 7pm and 9pm, when all of the soaps are screened.
Jill Partington, from the charity, said, “We like our soaps to reflect our reality and people’s bad habits are part of this.
“In the real world if you are caught littering you will be fined, it is illegal after all!”
