Coca-Cola's business practices are being investigated in a Channel 4 Dispatches programme next week.

The programme, Mark Thomas on Coca-Cola, airs on 19 November and will explore accusations of child labour in El Salvador and claims Coke used death squads in Columbia to target union leaders, leading to a boycott of Coca-Cola products in UK and US universities.

A spokeswoman for Coca-Cola said the company was aware of the programme and was planning to watch it.
