The FTSE 100 has fallen into the red after a late start to trading due to technical issues.
With trading kicking off an hour later than the normal 8am start, the UK blue-chip index edged six points lower to 7,706 points, as shares trading without entitlement to their next dividend weighed on the index.
But the big movers were to be found outside the FTSE 100. Among 'mid-cap' stocks, Auto Trader (AUOTA) jumped 8.3% to 383.7p after a strong earnings update.
Capita (CPI) was close behind, rising 6% to 148p after an upgrade from analysts at Citigroup.
Kier (KIE) fell to the bottom of the index, down 6.4% at £10.12 as analysts at Barclays slapped an 'underweight' rating on the shares.
