After publicly criticising the Ashanti King, Otumfuo Nana Osei Tutu II, journalist Afia Pokua had to apologise following a strict traditional protocol. BBC Africa's Daniel Dadzie explains how royal apologies work in Ghana, and why Afia didn't get a pardon. Plus, how to say 'I'm sorry' in Urdu, Russian, Korean, Chinese and Tajiki - and why some people in Hong Kong feel taxi drivers owe them an apology, with Martin Yip from BBC Chinese.
