Did you read durhamjen's link? If not, to summarise:
The DWP has been forced to release secret documents illustrating how they control and manipulate the media:
The DWP monitors and analyses both mainstream and social media to reduce and manage negative coverage.
The reports show that on a nearly monthly basis from March 2014 to September 2015 the DWP “spiked” (persuaded journalists not to run) a total of 385 stories.
In August 2015 the DWP “proactively briefed” the media about long-awaited statistics which showed the amount of ESA claimants who had died after being found fit for work, and successfully spiked coverage in a range of news outlets.
The reports confirm that the DWP considers the right-wing press to be supportive of them, and highlights cases where they have used them to “set the record straight” and further government policy.
Without actually having a process whereby the government blatantly censors press stories, it appears that there is a more informal mechanism used to prevent stories from being aired. This principally seems to be the co-operation of "the right wing press" - and the majority of our papers and their proprietors are right wing - in ignoring or manipulating stories that reflect negatively upon the government's policies.
How then can we say we have a "free" press? It may be freer than in some countries but why must we always excuse our own position by pointing to somewhere else where the situation is even worse?
