And it wasn't only one warning either. Cameron dismissed the criticism of his communications director hire. The Guardian:
The former Liberal Democrat leader, who had been extensively briefed on details that had not been made public for legal reasons, was so convinced that the truth would eventually emerge that he contacted the prime minister's office.
Ashdown, a key player as the Liberal Democrats agonised over whether to join in a coalition with the Tories, told the Observer that, based on what he had been told, it was obvious Coulson's appointment as Cameron's director of communications would be a disaster.
"I warned No 10 within days of the election that they would suffer terrible damage if they did not get rid of Coulson, when these things came out, as it was inevitable they would," he said.
