Debate/Election

The language is formal, talking about politics seriously, though still being off-handed and shaming the Labour party through their use of visual codes and language. By saying "Runaway Jihadi's Father is Labour Activist" they make a link between the Labour party and terrorism, which is a very controversial subject which has been a hot topic for a few months with ISIS and the Charlie Hebdo attacks. Because Ed Miliband's photo is larger than the actual suspect to the arrest, it makes him seem worse, and more guilty than the actual offender.

The Mode of Address is formal, since the Daily Mail are trying to post a slam article against Labour, if it was informal, it wouldn't be taken as seriously. By using formal language, they stress the importance of the subject, even though the Labour Activist isn't important enough of a supporter, or integral to the campaign to be named in the headline, like an MEP or other Labour supporters might be.

The people in control of the messages and values in the text are the writers, and editors, Chris Greenwood and David Williams, though they are biased in favour of the Tories.  The ideologies and messages don't directly support the Conservative party, but they make the other parties look worse, making themselves look like the lesser of two evils.
