Dialog Semiconductor slumped to the bottom of the Stoxx 600 on Monday morning after admitting that its biggest customer Apple could be about to design its own chips.

In mid-morning European trade, shares in the Anglo-German firm were more than 18 percent lower. The slump built on a similar fall in value last Thursday when a news report claimed Apple would be designing its own iPhone chips from as early as next year.
