European Commission to reveal plans to change data privacy laws

Businesses have expressed concern about proposed EU data protection rules which include a "right to be forgotten".

The European Commission is revealing the planned changes at a conference on Wednesday.

It has already said that individuals would be able to ask for data about themselves to be deleted unless it was being kept for a "legitimate" purpose.

The BBC's technology correspondent Rory Cellan-Jones explained what was at stake.
