UK Prime Minister Boris Johnson has endured and enjoyed a year that was impossible to predict. In January, top on his agenda was Brexit while he was still enjoying his general election triumph of the previous month, won partly on the back of campaigning for Brexit. The decision of a UK royal to retire from the spotlight of family duty would be the defining moment of most years – in 2020, it was just another ripple. The Duke and Duchess of Sussex moved to the US via a stop in Canada and the British Establishment coped and moved on. That was before coronavirus spread, battered the economy, killed tens of thousands of people and quickly became the most grave public health catastrophe since the Second World War. Mr Johnson enforced a national lockdown in March and his government is still battling successive waves of Covid-19, most recently a more infectious mutation of the disease that first appeared in London before threatening to spread abroad. The prime minister himself was admitted to hospital having contracted the virus and needed intensive care treatment. On a cheerier note, Mr Johnson and his fiancee Carrie Symonds in April announced the birth of their baby boy named Wilfred. Now, with the end of the year approaching, Mr Johnson appears to have guided Britain into post-EU life successfully. How Britain handles that and the continuing Covid-19 pandemic will be his legacy. The job he always dreamed of has proved more demanding than he could ever have imagined.
