The regulator was singled out by the Tory leader as the starting point for his planned cuts to the number of quangos should he come to power.
During a speech to the Reform thinktank yesterday, Cameron claimed that under a Conservative government, "Ofcom as we know it will cease to exist".
His inflamatory rhetoric prompted Ofcom to respond, citing the fact that it was formed out of a merger of five different media and telecoms regulators. It said this was evidence that its existence represents a move away from quangos.
The regulator, speaking to The Guardian, highlighted its reduced headcount and saving of £117 million over the past five years in a bid to reassert its value to the media and advertising sectors.
Meanwhile, Ben Bradshaw, the culture secretary, also criticised Cameron’s plans, claiming that he misunderstood Ofcom's role.
