Implement a Covid Windfall tax on companies which profited from the Covid Crisis

Many businesses and employees operating in the UK have suffered great hardship as a result of the Government's policy responses to the Covid pandemic. There are, however, some, mostly large multinational companies and their senior executives, who've massively profited from these responses, e.g. pharmaceutical companies. The Government have now announced an increase in overall taxation on the British people to the highest level ever. A windfall tax would reallocate the tax burden.
