Kiss was the only one of the big four London commercial radio stations to lose listeners in the breakfast slot in the three months up to 28 June.
Bauer stablemate Magic came second with 922,000 (up 23.4 per cent versus Q1) and Heart London was third with 887,000 (up 41.5 per cent versus Q1).

Kiss saw the biggest increase in reach in Q2 2015 compared to Q2 2014, a 14 per cent increase gave it a total reach of 2.12 million, which was second biggest overall.
Magic had the third biggest reach at 2.00 million, up 3.6 per cent versus Q2 2014, closely followed by Heart on 1.99 million, up 8.1 per cent over the same period.
