Does the BBC have a left wing bias?

I used to believe the BBC was the envy of the world and it told the news in an unbiased manner.

However over the last decade I've changed my mind and now think the BBC is an embarassment to the UK and it is biased. I watch the news on the BBC and it's constantly attacking Trump and pushing a pro EU/ pro immigration agenda.

The BBC continually tell us that immigration doesn't effect wages in the UK. However any person that understands basic economics would agree that flooding a country with workers reduces wages. It's simple "supply and demand". If the BBC are willing to lie to us over things like that it's obvious they are lying to us over other things.

Trump is right. The BBC is "fake news".
