What a novel way to run rule a country!

Newt Gingrich has pledged that on his first day as president he will set up a constitutional showdown by ordering the military to defy a supreme court ruling extending some legal rights to foreign terrorism suspects and captured enemy combatants in US custody.

The Republican contender told a forum of anti-abortion activists ahead of South Carolina's primary election that as president he would ignore supreme court rulings he regards as legally flawed. He implied that would also extend to the 1973 decision, Roe vs Wade, legalising abortion.

"If the court makes a fundamentally wrong decision, the president can in fact ignore it," said Gingrich to cheers.
