One way newspapers are effective is because they are allowed to show bias. This means that as we live in a democracy we have a free press which means we can criticise the government. Most newspapers support a certain party will print good things about them. They will also print negative stories about the party they don't support. For example, on the 12th December 2019 (general election day) 'The National' newspaper in Scotland headline was "If you want independence, vote SNP." The Daily Mail headline encouraged voters to "Back Boris."
