This week’s decision to give the adjudicator the power to fine retailers if they step out of line is exactly the right one.

For years supermarkets have had free reign to demand cash back from suppliers whenever they are unhappy or deemed it necessary.

It’s quite right that if a body is being given the job of policing the sector then it also has the power to enforce the law through fines where abuses of the system are found to have taken place.

Now it’s up to suppliers to trust the system and step forward – anonymously of course – to bring any grievances to light.

On a lighter note, hats off to the Chinese this week for taking the issue of local food to a whole new level – Mars to be precise.

According to Chinese media, plans have been drawn up to feed astronauts from veg plots on the moon and other planets.

The kind of people that get upset about veg flown in from Kenya will presumably spontaneously combust when they hear about this. It certainly puts the food miles debate in a new light.

I have visions of a space-suited Hugh Fearnley-Whittingstall poring over his crops and despairing that an Intergalactic Tesco Extra has just opened up at the Sea of Tranquillity.

It couldn’t happen. Could it?
