Not really. Boris outright lies all the time, and he's rarely picked up on for it. There are also several instances of Newspaper's running stories on the exact same policy, positively when suggested by the the Tories, and negatively when suggested by Corbyn. You can't get much more objective bias than that.
No, it wasn't.
The lies about it being a setup were started shortly by the unnamed sockpuppet trolls and spread fast. The media can't seem to fight this

It wasn't. There's an official statement from the hospital confirming they had no beds left. Of course, the media chose to report it, but they aren't lying.
The right-wing media lied about it though, and it's a very relevant example of online disinformation:
"Despite the claim that the photo was staged having been acknowledged as false, it [the claim] has continued to spread on both Facebook and Twitter [...] Telegraph columnist Allison Pearson retweeted screenshots of the Facebook page to her followers twice, telling them “I presume this is genuine”, and adding later that the photo was “100% faked”. Her posts have received thousands of retweets between them."

(This is already downvoted, along with every non-pro-Tory comment in this discussion. Probably it will recover, HN usually does, but it would be better if people who disagree counter the arguments, rather than just downvoting what they're uncomfortable with.)
Even if we're acknowledging that this story wasn't a setup, it's wrong to suggest that there's more right-wing bias in British media than left. It's probably about the same, though of course some establishments will always have particular leanings (e.g. Guardian to the left) Even the Beeb, which one would assume is neutral, regularly jumps on the Boris-bashing brigade.
So again, no, it's not "both sides do it". It's mainly the right.
It's been proved beyond any doubt that the boy sleeping on the hospital floor was in fact true[0], despite an army of twitter and facebook bots being deployed to try and discredit the story[1]. The hospital involved publicly apologised for the incident.

(Our local "anti-Zionist" friends in Labour will mod me down for this, I know.)
Maybe someone has made a systematic review of the reporting of Conservative and Labour racism, and the reporting of it, but just throwing up a statement like yours, without also including the racism of Conservative party members/leaders, is just fuelling the fire of hostile debate.
There will be racist people in both parties. Step back, and compare the depth of the racism and the number and influence of the people involved.
But if we're playing the "which one is really worse?" game, instead of striving to better either, we've lost.
