Ryanair rapped over low emissions claims
Copyright: ReutersMore on advertisements that have fallen foul of guidelines.
Claims made by Ryanair about its carbon emissions have been banned by the UK's advertising watchdog.
Europe's biggest airline by passenger numbers had billed itself as the region's "lowest emissions airline" and a "low C02 emissions airline".
But the Advertising Standards Authority ruled Ryanair's claims in press, TV and radio adverts could not be backed up.
Ryanair hit back in a statement saying consumers could halve their carbon footprint if they switched to it.
Pretty Little Thing: 'Overly sexualised' advert banned
BBC Radio 5 Live
Copyright: Pretty Little ThingAn advert for fashion retailer Pretty Little Thing which featured women wearing exposing lingerie has been banned for being "offensive".
The YouTube ad presented the firm's products in an "overly-sexualised way" and depicted women as sex objects, the Advertising Standards Authority said.
The retailer is one of several online fast fashion companies to have been rapped for their racy marketing.
Pretty Little Thing said it "in no way meant to cause any offence".
Rania Robinson, chief executive of creative agency Quiet Storm, told Radio Five Live's Wake Up to Money programme: "I don't think we need to have ads like that, but.... they clearly have a lot of appeal."
She says the models featured in the Pretty Little Thing advert were "heavily made up and sexualised".
Ms Robinson said from a sizing point of view the ad in question "featured all shapes and sizes", but she questioned whether the portrayals were an accurate representation of wider society.
