UK frozen fish processors are not expected to step up their rate of stockpiling inventory, whenever a crucial vote on the UK's EU withdrawal takes place.

Companies supplying frozen fish, much of it in block form, have built up some two months' stock as a contingency against negative fallout from Brexit.

All eyes were due to be on the UK's House of Commons on Tuesday evening when lawmakers would have decided whether to rubber stamp or reject a deal on the terms of the UK's withdrawal that Prime Minister Theresa May is pushing hard for them to approve.
