Avocado-lovers can look forward to the arrival of an enormous variety five times bigger than the norm when it hits supermarket shelves this weekend.

The rare "Avozilla" - thought to be the world's largest avocado - comes from just four trees grown by one of the world's biggest suppliers of avocados in South Africa.
