(Sharecast News) - Airline shares weighed on the top flight index at the end of the week after falling afoul of a cascade of IT glitches around the world triggered by a update from cyber security outfit Crowdstrike.

Segro was another top faller on the FSTE 100 despite announcing the sale of a portfolio of logistics warehouses in Italy for €327m (£275m).

Shell also contributed to the Footsie's retreat, tracking a 1.6% decline in the price of Brent crude oil to $83.75 a barrel on the ICE.
