She was furious when she found out her mobile phone had been tapped by the US National Security Agency. <br /><br />“It is the case that I don’t publicise the details of the work of the German [intelligence] agencies,” Merkel said in a statement.<br /><br />“What is necessary will be said and discussed in the parliamentary supervisory committee [PKGR] and there, as far as it is necessary, the parliamentary body will be given what further information they need,” she added.<br /><br />After her mobile phone scandal,Merkel famously said, “spying among friends is not at all acceptable.”<br /><br />Turkey’s largest trading partner in the EU is NATO ally Germany.
