Britain unveils its first post-Brexit budget on Wednesday and analysts expect Prime Minister Boris Johnson to press ahead with major spending on infrastructure, despite the economic fallout from the coronavirus.

Finance minister Rishi Sunak, who will present the budget after his predecessor Sajid Javid resigned unexpectedly last month, is also scheduled to outline emergency funding measures in the battle against COVID-19.

Before the novel coronavirus hit the headlines, Chancellor of the Exchequer Sunak had said the budget “will deliver” on recent government promises of “unleashing the country’s potential”.
