We reported yesterday about the fact that food from the UK may be banned from your luggage in the case of a no-deal Brexit.
In fact, this rule will be for any food of animal origin. So for example bacon, sausages, cheese would all be subject to increased controls, along with Bovril which is made from beef extract.
Non animal-based items should still be allowed, which means that marmite should be allowed.
Marmite: Yeast extract, water, salt, flavouring, spices.
Bovril: Hydrolysed vegetable protein (soy), beef stock, water, corn starch, salt, yeast extract, caramel, sugar, onion, thickener, spices, acidity regulators, anti-foaming agent, flavouring, flavour enhancer, eggs, vitamins, iron.
