Listeners abandon Radio 1

Radio 1's audience has tumbled to its lowest ever level following the abrupt departure of Chris Evans from its high-profile breakfast show in January.

The station lost 370,000 listeners in the first three months of the year, according to the latest Rajar audience research figures. In all, 10.3 million people were tuning into the station every week during the first quarter of the year. Meanwhile, Radio 5 Live - just three years old - was celebrating an extra 500,000 listeners, which took audience figures up to 5.5 million, its highest ever.
