London's FTSE 100 edges 2.3 points lower to 7,335.5 on Monday, with fears over a hard Brexit pushing sterling lower against the US dollar and giving a boost to miners including Fresnillo (FRES), up 14p to £14.27, BHP Billiton (BLT), bid up 7.5p to £14.62, Anglo American (AAL), up 1.6% at £13.51 and Randgold Resources (RRS), which puts on 75p at £67.85.

Temporary power provider Aggreko (AGK) gains 7p at 994.5p as investors cheer news of extensions to contracts in Argentina.

Asset manager Ashmore (ASHM) advances 5.2p to 288.7p despite a decline in second quarter assets under management, as CEO Mark Coombs says the strengthening in emerging asset prices seen in December has continued into the new year and flags a further strong performance in 2017.

European regional airline Flybe (FLYB) perks up 3.4% to 45.75p as Christine Ourmieres-Widener takes up the post as CEO, following on from the shock resignation of Saad Hammad in November.
