Rear brake light on drivers side stop working

Hi my rear lights on my discovery 3 2006 don't seem to be working 100%.

When my headlights are turned off my brake lights work perfectly but when I turn my headlights on my rear brake lights stop working when pedal is pressed.

Any suggestions?

Bad earth at the rear I expect.
Could be the brake lamp bulb holder dirty

As Pete said. What about the other lights at the rear, do they dim, if so definitley an earth problem.

The passenger side works perfectly just the drivers side when headlights are on and brake pedal pressed.

Have you tried replacing the bulb with a good quality item ?

Remove the drivers side lamp assembly and check the earth cable. While off check the connector for "crap" (technical term) and give it a good clean. Make sure all pins are available and not pushed back.
