One of the session's main fallers is Synety (SNTY:AIM), which collapses 27% to 100p after revealing a 34.5% discounted placing and open offer at 90p.

Industrial seals and security detectors manufacturer Smiths (SMIN) cheapens 0.9% to £11.67 on a 3% drop in first half pre-tax profit to £208 million, caused by adverse foreign exchange moves and tough trading conditions for its Detection and Interconnect divisions.
