Today the handcuffs come off in Nasdaq’s bid to take the London Stock Exchange. With 25.3pc of LSE shares, the American exchange can bid for the rest at £12.43 per share.

However, sources close to Nasdaq say it can’t afford to buy at that price, so is likely to sit out the next six months. The New York-based company is already heavily in debt and may refuse to gamble, especially as it is now known the British Government intends to legislate to protect London from the onerous American Sarbane-Oxley rules and may pack off any bid to the Competition Commission.

The Times (London) reports : “… there were signs at the weekend that some investors were taking the view that, in the short term at least, the LSE share price could fall in the absence of a bid or an agreed deal. About 12 per cent of the shares are the subject of stock borrowing, a technique that is often used to go short in a share in the expectation of a fall.”

Speculation grew that Clara Furse may seek a deal with a Far East exchange.
