It sounds like many civil servants are against the PM (years ago they were not supposed to reveal political affiliations, but that seems to have gone by the board) Being opposed to lying and corruption is not a political position, it is an ethical position. Civil servants, like everyone else, have always been allowed to have ethical positions.
Anyway wrt The latest bombshell (about the Afghan animal rescue) apparently came from a civil servant in Zac Goldsmith's office it was not leaked was it? It went to a committee I thought?
Chucking mud at civil servants is just another desperate tactic to deflect, minimise, bullshit.
