The Armed Forces are to provide up to 3,500 extra troops for security duty at the Games after a private firm admitted it could not supply enough guards.

In a humiliating move, Home Secretary Theresa May has been forced to plead with the Ministry of Defence to release thousands more service personnel to work as security officers at London 2012.

In his recent Michael Kirby Lecture, Malcolm Turnbull made an excellent case for same-sex marriage that came to an appalling conclusion, civil unions.

Part of the problem is that Turnbull has his facts wrong.

For example, his claim that civil unions are "better than nothing" has been shown by the overseas experience to be false.

Mitt Romney is betraying his calling.

He brings to the presidential race a record of accomplishment to which few White House contenders can lay claim: W. Mitt Romney knows how to make money.

Some may argue that a money-making ability alone is no qualification to be president. I agree that having a high net worth is insufficient reason to be declared presidential timber.
