Capital gains second place
Capital FM is now London's second favourite commercial radio station, as Heart slips to third place.
Both stations, owned by Global Radio, just miss out on the title of London's most listened to commercial station, which continues to be held by Bauer Media's Magic 105.4.
Magic remains the undisputed number one, on both reach and hours, as the station retains just over two million listeners, and increases share.
Capital FM, which still has the most listened to breakfast show with Johnny Vaughan and Lisa Snowdon, has seen a high rise in hours quarter on quarter, and its highest market share since December 2004.
Heart has seen a drop in share and listeners in London, but still has fewer than two million people listening each week.
Elsewhere, LBC has achieved its highest ever reach in 14 years with 956,000 people tuning in, with an average of 12 hours. Xfm's new breakfast presenter Ian Camfield has seen a 19 per cent increase since this time a year ago, but the station has lost a small amount of listeners this quarter.
GMG's Smooth Radio is up on each almost 50 per cent from 12 months ago, suggesting the station is finally heading in the right direction after numerous format changes, and Punjabi Radio (was Yarr Radio) has had the biggest increase, with 34,000 listeners compared to 18,000 a year ago.
