Should Turkey join the EU?
In a speech at the Turkish parliament, Mr Cameron said he wanted to "pave the road" for Turkey to join the EU, saying the country was "vital for our economy, vital for our security and vital for our diplomacy".
He went on to say Turkey could become a "great European power", helping build links with the Middle East. Turkey opened accession negotiations with the EU in 2005 but is considered very unlikely to join in the next 10 years, partly because of opposition from countries such as France.
Is the prime minister right to advocate Turkey's membership to the EU? Will Turkey's inclusion help build links with the Middle East? Has the EU grown too large? Is opposition to Turkey's membership driven by protectionism and nationalism?
