Is Brexit or Covid to blame for Britain's supply chain crisis?

Contributing sentiments towards policy:

62% : As the crisis spread to petrol supplies on Friday, the transport secretary, Grant Shapps, dismissed claims that Brexit had caused the problem, insisting that Covid was the "main reason".
60% : The Labour party, which has largely avoided commenting on Brexit since January, blames lack of planning in the face of countless warnings over shortages of EU nationals in the workforce.
54% : But industry bosses say it is the cliff-edge cause by Brexit with a lack of British workers filling the gaps left in the haulage industry, warehousing, hospitality and the meat production sectors.
54% : With the pandemic and Brexit already taking its toll, a winter of wage inflation is not the answer.
49% : "The pandemic is the cause, but Brexit is limiting our options for solutions," said Shane Brennan, the chief executive of the Cold Chain Federation, which represents chilled and ambient food warehousing owners.
46% : It is convinced Brexit is the solution as it can prod British employers to wean themselves off a low-wage culture and recruit and train local staff.
