Labour MP for Tottenham David Lammy investigates the modern concept of "tribes" and how New Tribalism has pernicious effects on the health of our society.

Tribes will explore ways in which we can challenge and neuter New Tribalism, distinguishing between the 'good' sort of tribalism - the patriotism that is inclusive and open to newcomers, the ethnic or religious pride that celebrates a particular culture or faith tradition rather than denigrates others as inferior, the 'Spirit of Dunkirk' that saw ordinary people come together and do extraordinary things - from the harmful tribalism that excludes, denigrates and divides.
