If you look in the last pic you can see a gold coloured piece of metal on the end of a plastic arm. A pin had come loose which caused it drop down away from the handle. I should look like this...
You will have to get in the boot through the back seats, take off the trim either side of the parcel shelf then unscrew and remove the boot trim. Find the pin inside the boot lid and put it all back together. I guessed mine only broke because the pin had slowly worked its self out over the past 12 years, its been fine since.
