SUPPLIES of satsumas to the UK could be reduced because of falling worldwide demand.

The UK is the world's biggest importer of the fruit but a drop in sales in other parts of the world is forcing growers to switch to more profitable crops, such as clementines and oranges.

Firm Munoz Mehadrin, which imports satsumas to the UK from countries around the world, warns that supplies to the UK could be threatened if the trend continues.

A spokeswoman said: ''It is a potential risk. If growers aren't seeing the returns they need then they will produce less.''

Supermarket chain Tesco, which sells around 25 million satsumas a year, says its supplies are safe for now.

It has launched a campaign called Save Our Satsumas, in which it will stress the importance of the crop.
