Again, as mentioned, I gave the 1943 example to point out how recent such colonial actions and attempts at ethnic cleansing were. There are people alive today who suffered through that.
There's ample examples of other genocides via famine performed by the English against ethnic groups they were subjugating at the time. For one closer to home, lets look at the English activity behind the Irish famine.

Baronet Charles Trevelyan was one of the engineers behind that famine. Interestingly enough he had honed his skills of bulk-murder in India.

"The real evil with which we have to contend is not the physical evil of the Famine, but the moral evil of the selfish, perverse and turbulent character of the people"
"Famine is an effective mechanism for reducing surplus population"
As usual, such individuals used all manner of tools to justify the genocide of any ethnic group they deemed "inferior". In this case, the Irish. It is telling that one of the major tools was that precise instrument of religion with Trevelyan even describing the famine and subsequent mass death as an instrument of God.
