The UK tea company, Tetley, has been told by the advertising watchdog, the Advertising Standards Authority (ASA), to withdraw ads which make what are perceived to be exaggerated health claims about its tea.

The company's new £15m campaign which boasts its tea is "rich in antioxidants that can help keep your heart healthy", has received criticism. The ASA said the purported health benefits of drinking Tetley tea had not been proved.
