Officials from the airline Swiss said Monday that they have asked stock market authorities to suspend trading its shares to minimise uncertainty on the market before a board meeting on Tuesday. Swiss is the target of a possible takeover by German airline Lufthansa. At the close of trading on Friday, Swiss shares were being quoted at 9.60 Swiss francs (6.18 euros) per share. They had been priced at less than 9.0 francs at the beginning of March but have risen strongly since March 10 in response to rumours of interest by Lufthansa.
