London's FTSE 100 slipped on Wednesday, as a fall in oil prices following US President Donald Trump's decision to halt negotiations with Congress for a US stimulus knocked energy stocks, while Tesco gained after reporting a jump in sales.

The blue-chip FTSE 100 index fell 0.2pc, with energy and insurers leading the declines.

The mid-cap index was up 0.1pc.

The energy index was also the biggest drag on the FTSE 100 as oil prices fell more than 1pc on Trump's decision and a larger-than-expected increase in US crude inventories.

"The market is in belief that there will be a stimulus package coming anyway irrespective (of) who wins the US elections.
