* No-deal Brexit fears cap gains
* All eyes on BoE meeting on Thursday
* BP drops after it forecasts weak crude demand
* Security firm G4S marks best day ever (Adds details, comment, updates to close)
Sept 14 (Reuters) - London’s blue-chip index fell on Monday as the prospect of waning demand weighed on heavyweight energy stocks, while security firm G4S propped up the midcap index after it rejected a takeover from Canadia’s GardaWorld.
The blue-chip FTSE 100 shed 0.1%, with oil and gas major BP weighing the most after it forecast declining fossil fuel demand due to climate policies and the coronavirus epidemic. Oil prices were steady.
The mid-cap index added 0.7%, with G4S surging to a near seven-month high after it rejected a 2.95 billion pound ($3.8 billion) offer from Canadian security firm GardaWorld, saying it was “highly opportunistic”.
Divorce talks between the United Kingdom and the European Union continued to be at the forefront, with the bloc ramping up pressure on Prime Minister Boris Johnson to step back from breaking the Brexit divorce treaty.
“Brexit is back with a bang, and there’s a growing risk that the transition period will end with no trade agreement in place between the UK and the EU,” ING economists wrote in a note.
Markets are also awaiting Thursday’s Bank of England policy meeting, where it is likely to signal more stimulus to lift the economy out of a deep recession that could be exacerbated by a messy Brexit.
While steady stimulus has helped the FTSE 100 bounce from its coronavirus lows earlier this year, surging cases and middling economic data have seen the index stall in recent months, with new Brexit fears also expected to weigh in the near-term.
