First Minister Arlene Foster has told BBC News NI that she is unaware of any changes to emails relating to the controversial 'cash-for-ash' scheme that removed references to her or her department.

Mrs Foster was speaking to BBC presenter Stephen Nolan.

Former Stormont minister Jonathan Bell has claimed that DUP advisers tried to "cleanse the record" by removing all references to the first minister and her department on emails linked to the Renewable Heat Incentive (RHI) scheme.
