Selin Sayek Böke, Deputy Leader, Turkey's Republican People's Party

Zeinab Badawi speaks to Selin Sayek Böke, Turkish opposition MP and deputy leader for the Republican People's Party the CHP. In mid-April Turks vote in a referendum to change the country's constitution and give the president more powers. Polls suggest it's a tight race, so the votes of Turkish citizens living in Europe could help swing the result. But government ministers have been prevented from campaigning in some European countries provoking a major diplomatic row. The CHP is opposed to the referendum claiming it would give President Erdogan too much power. But do they have an alternative vision for Turkey that can challenge the popularity of the ruling AK Party?
