This is just ridicolous. The british royal family was massively involved in the slave trade.

Also claiming the british empire was the first "major world power to abolish slavery" is rich, given that the empire became a world power because of slavery and genocidal colonization. Also it nicely ignores, that the british were still well involved in slave trade outside the mainland. A slave trade that was also genocidal, as hundreds of thousands of enslaved Africans died even before reaching America.

But British people skewing and denieing their history of slavery, genocide, robbery and brutal opression is typical. I hope the fallout of Brexit finally gets them off their high horse and onto the ground of reality.
