The reversing lights and audible signal from the reversing sensors fail to operate. The vehicle is a Vauxhall Astra convertible turbo 2003 with factory fitted reversing sensors.

The fact that 2 different things that are operated by the gearlever selecting reverse have stopped working suggest that either the fuse has gone or the reverse light switch on the gearbox has packed up.
I would start by checking the fusebox and finding the correct fuse for the reverse lamps and seeing if it's blown. If it has replace it and see what happens next.
