The London markets and the pound both slipped into the red as traders remained cautious ahead of Saturday's Brexit vote.

The FTSE 100 closed 31.75 points lower at 7,150.57 at the end of trading on Friday.

David Madden, market analyst at CMC Markets UK, said: "When it comes to tomorrow's all-important Brexit deal vote, traders are curtailing their positions as the vote is tipped to go down to the wire.

"The bullish mood that we saw during the week on the build up to the deal being brokered and announced, has now been replaced with a more cautious outlook."

The lack of optimism dented sterling, halting its recent rebound slightly, to push it down against both the dollar and euro.

The pound was down 0.02% versus the US dollar at 1.288, and down 0.19% against the euro at 1.156.

Mr Madden added: "The pound saw major volatility this week on account of the Brexit goings on, but on Friday the mood was much more muted.

"Many dealers are playing the wait-and-see game as all eyes will be on Westminster."

The European markets also drifted on the back of pessimistic statements by Mario Draghi, head of the European Central Bank.

Mr Draghi said there are some "mild signs of overvaluations in the euro area", weakening sentiment in European equity markets.

The German Dax decreased by 0.17% while the French Cac moved 0.65% lower.
