A divided Colorado Supreme Court has declared former president Donald Trump ineligible for the White House under the US Constitution’s insurrection clause and removed him from the state’s presidential primary ballot.

The decision sets up a likely showdown in the nation’s highest court to decide whether the front-runner for the Republican nomination can remain in the race.
