Turkey – located between big energy producers and the EU market – is crucial for Europe’s energy security. However, plans for the Nabucco pipeline as an alternative to Russian gas supplies are in trouble.

Turkey is about to give itself a new constitution. That is good because the current one was written by the army in 1982, after the last military coup.

Sir,Geoffrey Wheatcroft rejects David Miliband's arguments for keeping the European Union's door open for Turkey ("Structural flaws in Miliband's Turkish bridge", September 10). Like most critics of Turkish accession, he argues that the country is too big, too poor and too Muslim. Like most critics, he is short-sighted.
