British journalists have been digesting the first day of arguments at the Supreme Court. Here's what a few of them made of it all.

The BBC's Dominic Casciani noted that much of the debate was focused on whether the prorogation was a political matter, or one for the courts to weigh in on.

Carl Gardner, who served as a government lawyer for 12 years, suggested that Gina Miller and Joanna Cherry's teams will be happier than the government's at the end of day 1.

Legal expert Joshua Rozenberg picked up on a few queries the judges had for the government's lawyer, Lord Kerr, at the end of the day's proceedings.

But barrister Adam Wagner also felt the government could have ground to make up.
