According to extracts released to the media in advance of his speech, Mr Miliband will describe his enthusiasm for ethnic diversity in the UK.
"We are stronger for it - and I love Britain for it. It gives us access to new ideas, new perspectives, new energies," he will say.
"But at the same time we know there is anxiety about immigration and what it means for our culture. The answer is not to sweep it under the carpet."
In part, that means rejecting the idea that people can "live side by side in their own communities, respecting each other but living separate lives, protected from hatreds but never building a common bond - never learning to appreciate one another", he explains.
