A spokesperson for Next Day Delivery, which conducted the study, said: “With the country facing significant delays in the delivery of food and other essentials, the experiences of families in the UK – particularly in London, where food shortages are hitting hardest – give us a clear picture of how the situation is impacting our everyday lives.
“With Christmas approaching, the pressure will be on to resolve the various supply chain issues (including driver vacancies and CO2 shortages) so that warehouses can remain stocked and consumers can purchase the essential products they need.”
More than a third of Londoners were not able to purchase petrol for their cars in the past two weeks due to fuel shortages, according to the research.
