Thanks for all the suggestions chaps......
It really needed some reinforcement, so I had a nose around the garage and used a small piece of wood and cut it down (1cm X 10cm, roughly) so that it fitted quite snuggly into the recessed handle part of the drawer, where it had cracked right in the middle. This gave sufficient support / strengthening, but looked awful, so I covered the wood with 3M's self adhesive metal repair tape, which has a chrome finish, which also helped to secure it to the plastic drawer handle.
It looked pretty good, and functions fine - wifey say's its good, and she's very fussy. So far, so good, been on a while now, but time will tell if it holds out..... Beats over £30 for a new drawer, just a bit of time and effort, ha ha
