Joe Biden unveils blueprint to overhaul US Supreme Court and presidential immunity, but chances of it succeeding are slim

"In short: Joe Biden has unveiled a plan to overhaul the Supreme Court, and proposed a constitutional amendment which will eliminate broad presidential immunity from crimes committed while in office.

"His proposal for the Supreme Court would see term limits introduced for its nine justices, who would also have to abide by a new code of conduct.

"What's next: To become reality, the plan would need to pass through Congress with a two-thirds majority, something unlikely given its current divided make-up."
