[HIGHLIGHTS] King Charles III, ill: what is the succession to the throne in the British crown like?

Since 2015, the succession to the British throne has followed the first-child rules. William, born June 21, 1982, is first in the line of succession.

Charles III's successor is his eldest son, Wiilliam. The first time this rule had consequences was when Prince Louis of Cambridge was born in 2018, instead of precede it, as would have happened if the old rule continued in force. The British line of. succession is separate from, but symmetrical to, the lines of succession in the other fourteen countries, unless the. constitution of the kingdom, specifically refers to the UK succession rules.
