> Can you show me any story on BBC that is biased to the right?

They're saying that the BBC is relatively impartial, not that it is biased to the right.

If you're saying that the BBC has left-biased stories, and therefore the claim of impartiality requires evidence of counterbalancing right-biased stories, I think you need to start by providing evidence of the former. (Even if you think it's blindingly obvious that the left-biased content exists, your examples will clarify what would be required to balance it out.)

> BBC is highly skewed to the left. No debate on that.

The fact that you argued that shows there is some debate. ;)

> Can you show me any story on BBC that is biased to the right?

No, because my point is that it isn’t biased to the left nor right.

What the BBC does is offer both sides of the political spectrum to have equal time sharing their arguments.

If you think that’s biased then what you’re actually saying is that the left deserves less time than the right. Thus it’s not the BBC exhibiting bias.

Is the BBC highly skewed to the left, or is reality?

I don’t think this is the flex you think it is.

their treatment of Israel-Palestine

or, both in modern times and during 'The Troubles', Ireland.

Biased does not mean it has to skew to a certain political leaning all of the time.

I hope you're being sarcastic. If you do want a debate, there's plenty of research on bias at the BBC, and there are examples of bias left and right, pun intended.
