It is the latest bid to push killers to come to court because threats of more time behind bars are unlikely to deter them if they are already facing years of incarceration.
The powers, due to take effect next year, will also apply to those removed from their sentencing hearing for disruptive behaviour.
Southport killer Axel Rudakubana was sentenced in his absence to a minimum of 52 years for the attack in which he murdered three young girls, after he refused to come into the courtroom and had been removed from the dock earlier in the day for shouting.
At his sentencing hearing at Liverpool Crown Court, Rudakubana interrupted the judge multiple times, saying: “I feel ill, judge. I feel ill. I’m going to pass out. No. I can’t continue with this.”
The judge responded, “I’ve asked you to be quiet.” The prosecution was asked to continue but Rudakubna shouted: “I can’t continue with this, judge. No, no, it can’t continue, judge. I need to speak to a paramedic. I need to speak to a paramedic. My chest is hurting.”
As he was escorted out of the hearing, a member of the public gallery shouted “coward” at the killer.
