The fight for freedom of speech in Egypt

The retrial of two Al-Jazeera journalists in Cairo has been adjourned until 19 March after key witnesses failed to show up.

Baher Mohammed and Mohamed Famy have always denied any wrongdoing and, speaking to the BBC's Yolande Knell, the men vowed to clear their names.

They were arrested in 2013 along with their colleague Peter Greste and found guilty of aiding the Muslim Brotherhood.
