Orange is failing to keep pace with the increasingly competitive UK broadband market, it has been claimed.
According to analysts from Dresdner Kleinwort, the firm has remained inert while its UK rivals have cut prices, increased speeds and launched attractive new bundles.
Dresdner Kleinwort said: "[Orange has] failed to respond to any of the recent price cuts by its competitors, leaving us to believe it is happy to sit by for now and watch its customers disappear."
News of the comments come as Orange, which remains the fifth-largest broadband provider in the UK, has seen its subscriber numbers fall during the second quarter of this year.
The firm plans to arrest this decline with the launch of a TV advertising campaign set to run in the third quarter.
A recent survey conducted by Point Topic placed Orange bottom among broadband providers for its quality of customer service.
