ENGINEERING firm GKN and miners dragged the FTSE 100 into the red on Monday, with a broker downgrade for Just Eat also weighing on London's top flight.

The index closed down 0.13 per cent, or 9.75 points, at 7,214.76 with GKN the biggest faller, ending the day down 11p or 2.53% at 424.1p.

It came after GKN rejected a final £8.1 billion takeover offer from Melrose Industries, saying it "continues to fundamentally undervalue" the engineering giant.

Melrose shares closed 4.9% lower at 213.5p, making it one of the worst performers on the FTSE 250.

Miners Randgold and Fresnillo were also among the fallers on the top flight as they tracked metal prices lower, both falling around 0.8%.

Shares in Just Eat also took a knock following a downgrade from Deutsche Bank from sell to hold.

The takeaway delivery firm ended the day down 0.86% at 781.6p.

Fiona Cincotta, senior market analyst at City Index, said: "Dominating the loser board were the likes of GKN following another hostile bid from Melrose, and Just Eat following a broker downgrade.

"Precious metal miners Randgold and Fresnillo were also among the fallers tracing metal prices lower, as investors ditched safe havens such as gold in favour of riskier assets."

Low-cost airline easyJet topped gainers, closing 2.85% higher at 1,607.5p after Credit Suisse raised its price target for the company.

In currency markets, the pound was trading higher against the US dollar, up 0.3% at 1.397, and rose 0.2% versus the euro to 1.127.

Sterling could be set for another rocky ride on Tuesday when Chancellor Philip Hammond delivers his Spring Statement.

While no surprises are expected, any clues on how a future Brexit trade agreement could affect the British economy could see the pound react.

The Office for Budget Responsibility is also expected to revise its growth forecasts, as well as borrowing outlook.

Across Europe, the French Cac 40 closed marginally higher by 0.04% while the German Dax ended the day up 0.6%.

Brent crude prices dipped to around $64.29 per barrel from $65.22 on Friday.

David Madden, market analyst at CMC Markets UK, said: "WTI and Brent Crude oil are in the red today as traders continue to be worried about the scale of American output.

"Last week US oil production reached another record high, and dealers are anticipating an update from the Energy Information Administration (EIA) about US shale production.

"The Commitments of Traders (COT) report showed that speculators with bullish bets on oil dipped for the first time in three weeks, which indicates a change in sentiment."

In UK stocks SSE, which is in the midst of a merger with fellow Big Six firm Npower, closed down 1.87% at 1,233.5p.

It came as Npower revealed an operating loss of £56 million last year and said that 155,000 customers deserted it.

Npower's parent firm Innogy could itself be broken up as part of a deal between its parent RWE and E.On, putting the spotlight on the deal to merge with SSE.

But SSE said it does not believe that the merger should be affected.

The biggest risers on the FTSE 100 were easyJet up 44.5p to 1,607p, Pearson up 15.6p to 767p, Evraz up 11.4p to 448.5p and Admiral Group up 31.5p to 1,945.5p.
