Police forces are facing mounting anger over the arrests of protesters as the Queen's coffin makes its final journey to London.
Civil liberties campaigners and MPs sounded the alarm over police handling of dissent during events to mourn the Queen's death and mark the start of the reign of King Charles.
Two people have been charged in connection with breach of the peace in Edinburgh, including a 22-year-old man who appeared to heckle Prince Andrew as the Queen's cortege passed through the streets on Monday. A 22-year-old woman holding anti-monarchy sign was also charged.
