2 ways Shammy. The hard way is to dig it out with a very sharp spade then trim to size and replant (assuming you want to replant - otherwise burn). If replanting a large saw helps.
The easy way is to pour paraffin over it and torch it BUT BE CAREFUL THERE IS NOTHING VALUABLE OR FLAMMABLE NEAR. It will disappear but in a year or 2, like Arnie, it will be back but not as vigorous for a few years.
It's nearly impossible to kill but you could try with either several applications of a systemic weed-killer or even pour strong sodium chlorate solution over it if you don't mind what you kill.
