British corporation continued trafficking of enslaved Africans to Guyana 40 years after abolition

Letter written in 1847 to Sandbach, Tinne and Company's Liverpool office reveals it engaged in practice after receiving taxpayer-funded compensation, book says

When Britain abolished slavery, plantation owners from powerful families notoriously received huge sums in compensation, while those who were enslaved got nothing.

Now evidence has come to light that Sandbach, Tinne and Company - a corporation closely linked to the merchants who got the biggest taxpayer-funded compensation payouts - continued to traffic enslaved Africans illegally after abolition to Guyana, in South America.
