Professor Emma Murphy, School of Government and International Affairs, gave expert analysis for BBC throughout the Tunisian protests.
Commenting upon key events as they happened, including the departure of President Zine al-Abidine Ben Ali and the installation of the interim national unity government, Professor Murphy said: "It is absolutely necessary for the new government to give early and detailed indications that reforms of the political party and electoral laws will be initiated sooner rather than later, to make sure that elections - when they come - offer the possibility of a genuine transfer of power.
"It also needs careful timing: early elections may be necessary to convince people that change is coming, but premature elections without significant reforms to remove the pro-RCD (Democratic Constitutional Rally) biases will lead to new problems." (BBC Online, 18 January 2011)
In addition to providing comment and analysis for the BBC, Professor Murphy explained the background to the protests, the role of social media in the protest movement, and described the potential political changes in Tunisia to broadcasters and news media across the world.
