Bias At The BBC

I found these two paragraphs from this BBC story quite revealing:

But some, including the editorial page of the conservative National Post newspaper, have argued that the pair should have known what they were getting into when they signed up for the US Army, and should be sent home to face justice.

...

But south of the border, right-wing commentators such as Bill O'Reilly of the Rupert Murdoch-owned Fox News TV network have seized on the case, even calling for a boycott of Canadian goods if the pair are not extradited quickly.

Why is it so important to point out that The National Post is 'conservative' and that Fox News TV is owned by Rupert Murdoch?

Why don't their own reporters get such disclaimers? Why shouldn't this from a story concerning Israel:

But there is little sign that Israel is set to be more open about its nuclear activities, the BBC's diplomatic correspondent Jonathan Marcus says.

Instead read:

But there is little sign that Israel is set to be more open about its nuclear activities, the BBC's, Britain's leftwing and anti-Israeli public broadcaster, diplomatic correspondent Jonathan Marcus says.

Just wondering.
