While the new king has made a name for himself in the climate and social welfare spaces, he will have to work hard to tackle rifts within the royal family, potentially deal with an independence movement in Scotland, and face up to the long-standing challenge of Commonwealth nations that no longer wish to have the U.K. monarch as their head of state. Within the Windsor clan, King Charles’s younger son Prince Harry has renounced his royal trappings and moved to California with his American wife Meghan Markle, and his recent novel, Spare, does not mince words in spelling out deep-seated resentment that he claims they felt while at the palace. The King will have to either make peace with the new arrangement forced by Prince Harry or build bridges with his second son. In Scotland, Humza Yousaf has now taken the reins of the Scottish National Party after the long tenure of Nicola Sturgeon. While the party has numerous internal issues to resolve, there is a distinct possibility of another independence referendum, which would pose sharp challenges to the U.K.’s economy and society, particularly in a post-Brexit context. King Charles would also have to engage with Commonwealth nations such as Antigua and Barbuda, Australia, the Bahamas, Belize, Grenada, Jamaica and St. Kitts and Nevis — nations that have signalled their intention to appoint their own heads of state. To tackle and effectively deal with these challenges, King Charles III will have to continue to embrace modern values while carrying the mantle of hoary royal traditions.
