Damian Green received leaked information, and as shadow immigration minister he had a duty to bring that information to public's attention. The rank incompetence of the Home Secretary is most definitely of public interest, and that is exactly how the CPS saw the case. There was no breach of national security - Jacqui Smith got mad because she was made to look stupid and incompetent - so Damian Green got arrested for doing his job. Jacqui Smith claims not to have ordered the arrest, but how much pressure did she put on civil servants to stop her continued embarrassment?
Speaking outside Parliament, Damian said:
How much more embarrassment can Gordon Brown take from Jacqui Smith? Surely he has to sack her now?
"I'm obviously very pleased with the director of public prosecutions' decision this morning. "This has been an extraordinary period. One of my jobs as Conservative immigration spokesman is to expose the many failings of the government's immigration policy.
"That's precisely what I was doing in this case and that's why ministers were so embarrassed. "That has led to the first arrest of an opposition politician for doing his job since Britain became a democracy.
"I cannot think of a better symbol of an out-of-touch, authoritarian, failing government that has been in power much too long."
