Besides the Guardian is left leaning, so you will get no factual information from the Guardian.

“Your Major independent watchdog groups classify the outlet as follows:AllSides:

This is kinda on the dumb side, LM, as Allside looks at the bias but doesn't evaluate the Guardian regarding facts unless it departs for the moon in conspiracy theories, etc., so your contention you will get no factual information from the Guardian is entirely unsupported - as usual.

But Media Bias Fact Check does look critically at the facts:

Net Sifter
Media Bias/Fact Check (MBFC) rates The Guardian as having a "Left" or "Left-Center" bias and a "High" rating for factual reporting. MBFC bases its "High" factual rating on the publication's strong investigative reporting, proper sourcing of information, and a clean track record with fact-checkers.

MBFC
~Overall, we rate The Guardian as Left-Center biased based on its story selection, which moderately favors the left. We also now rate them High for factual reporting due to minimal failed fact checks in the last five years.

So your contention regarding no factual information from the Guardian is a convenient fabrication on your part.
