ped in deals on Thursday, Reuters reported. The pan-European STOXX 600 .STOXX. index was down 0.4 percent, while Germany's DAX retreated 0.3 percent and Britain's FTSE 100 fell 0.5 percent. Some of the largest individual stock moves were spurred by fresh M&A action, with shares in Berendsen soaring nearly 27 percent after French laundry firm Elis made a $2.6 billion offer for the British rival. Likewise shares in Swedish debt collector firm Intrum Justitia dropped more than 8 percent after it proposed a string of divestments in order to assuage European Commission concerns over its planned merger with Norwegian rival Lindorff. Shares in Italy's Fiat Chrysler were also weaker.
