Prize money reaction muted - Phillips

On Tuesday it was also confirmed Hawk-Eye will be used at Wimbledon for the first time during this summer's championships, although the protocol for consulting the system has yet to be finalised.

On the subject of equal prize money Phillips said: "We've had only two or three letters from people who are irate because they believe it is the wrong thing to do. I know some people have written into national papers saying it's wrong but it's been supported by most of the media, the WTA, the ATP and the Department of Culture, Media and Sport."

The Hawk-Eye technology, which is already in place at US and Australian Opens, will rely on cameras mounted around Centre Court and Court One that will capture 3D images of any disputed line call.

Large screens positioned so they can be seen by all spectators in the courts will show exactly where the ball lands. The introduction of Hawk-Eye at Flushing Meadows and Melbourne Park has been deemed a success but Wimbledon will be the first major grass tournament to employ the system.

All England Club chief executive Ian Ritchie believes grass requires a different process for consulting the technology compared to other surfaces.

At the US and Australian Opens players are allowed two unsuccessful challenges during a set and one more in a tie-break.

Ritchie said: "We're looking at the options available to us at the moment. It's unlikely we'll implement unlimited challenges. We're considering the possibility of an extension but there's a balance to strike with the continuity that was evident in the US and Australian Opens.

"Different situations can arise on grass courts where the service is especially important. We're looking at the alternatives - maybe a limited extension to the number of challenges. But unlimited challenges are not an option."

Hawk-Eye, which is subject to final testing next month, will only be used on Centre Court and Court One while the existing Cyclops technology will be moved to Courts Two, 14 and 18.
