European stocks edged lower on Thursday as traders gauged mixed earnings from blue-chip companies such as Nestle and Deutsche Bank, while big M&A news in the mining sector powered Britain's FTSE 100 to fresh peaks.

Earnings in the first quarter are expected to decrease 12.1% from a year-ago period, according to LSEG data on Tuesday.
