The FTSE-100 fell on Monday.
Glencore lead the fallers as the miner faces a criminal probe over allegations of corruption in the Democratic Republic of Congo.
Other decliners included consumer shares such as Diageo and Unilever.
Notable risers on the FTSE 100 included security software group Avast and Kingfisher.
But they were unable to counter the overbearing weight of selling from FTSE majors HSBC, BP and Shell, all down.
An increase in the gold price was seen as one reason for a spike in Petropavlovsk shares. The gold miner specialises in digging for the yellow metal in Russia.
The FTSE 100 still remains about 18% below its January record high and concerns are growing that a second wave of infections could cause more disruption to businesses.
