On the FTSE 250, builder Galliford Try slumped 17 percent to its lowest since August 2012 after saying it was undertaking a strategic review of its construction business which would reduce its size and lead to a fall in annual profit.
But helping the mid-caps post carve out gains was emerging market-focused asset manager Ashmore which rose 2.5 percent after reporting a double-digit jump in assets under management.
JD Sports Fashion added 3.2 percent as acquisitions helped it tackle a challenging retail environment at home and post better-than-expected full-year earnings.
Drugmaker Indivior, recently battered by a U.S. Department of Justice indictment, was on course for its fourth straight session of gains with a 4 percent rise.
