Brenton Harrison Tarrant was jailed for life in August 2020, with no possibility of parole, after he plead guilty to the murder of 51 people and wounding 40 in the Christchurch terror attack.

Tarrant is now, five years later, attempting to overturn his conviction with claims he was not in a rational state when he plead guilty.

Criminal defence lawyer Steve Cullen spoke to Andrew Dickens about the appeal saying, "It's a very difficult situation for all, but we have to let the wheels of justice grind on and let it be dealt with properly so that hopefully, whatever the outcome is, we'll get finality and closure this time."

The New START treaty, signed by the United States and Russia in 2010, was a nuclear arms reduction treaty which has now expired.

US President Donald Trump has now called for a brand new nuclear treaty, prompting fears of a new global arms race.

International Law Professor Al Gillespie told Andrew Dickens, "Mr. Trump is the one who let it void, he was saying, well, it's not fair that only America has these restraints in Russia.

"He wanted other countries like China to also have restraints, but China wasn't interested."
