Have to love the last line,perhaps Dave will make a statement when he goes to court.
A former adviser to David Cameron has been charged with making and possessing indecent images of children.
Patrick Rock, 63, was arrested at his home in London in February after Downing Street contacted police.
He has been charged with three offences of making indecent images of children and one offence of possessing 59 indecent images of children.
The National Crime Agency (NCA) said the four charges cover offences allegedly committed between July 31 and August 31, 2013.
Asked about the decision at a news conference in Brussels, the Prime Minister said: "I won't be saying anything.
"It would be purely a matter for the courts and it wouldn't be appropriate to comment."
Rock has been bailed to appear at Westminster Magistrates' Court on July 3.
The NCA said the images have been assessed by Child Exploitation and Online Protection (CEOP) officers and Crown Prosecution Service (CPS) lawyers as meeting the definition of Level C.
Level C is defined as "indecent images depicting erotic posing with no sexual activity", an NCA spokeswoman said.
Rock, a special adviser on policy, resigned from his post a day before he was arrested.
He has been an influential figure behind the scenes in the Conservative Party for decades and made three unsuccessful bids to become an MP.
In the 1970s he was credited with coining the Tory slogan "Cows moo, dogs bark, Labour puts up taxes".
In 2011 Rock was drafted in by Mr Cameron - a fellow adviser to former Home Secretary Michael Howard in the 1990s - to beef up the Downing Street policy unit.
Prior to his arrest and resignation, he had been involved in drawing up government policy on internet porn filters.
