Uk's brexit deal may mean 'citrus marmalade' on labels, not 'orange marmalade'
The UK government is considering a food labeling agreement with the EU that could lead to a change in the way British marmalade is marketed, but it's not as drastic as some have claimed.

Eu rules allow wider use of term 'marmalade'
As part of a planned trade deal, the UK would align with EU rules allowing any citrus conserve to be labeled as 'citrus marmalade', so long as the specific fruit is mentioned. This means jars of orange marmalade would still be fine to call that.
Conservatives have accused Labour of unpicking brexit over the issue, but the proposed change is actually part of a 2023 agreement between the UK and EU, supported by Labour in Parliament. It would simply extend rules already planned for Northern Ireland to the rest of the country.
