** Shares in Tekfen Holding dip around 5% after the Turkey-based holding company, active in various sectors, reported a larger-than-feared Q1 loss
** Its Q1 net loss widened to 733.4 million lira from a loss of 732.9 million lira a year earlier
** Brokerage Global Yatirim states Q1 results were lower than expected, hence having a negative impact on the shares
** "We think that the turmoil in the company's board of directors during this period also reduced concentration on business lines," the brokerage says
** Tekfen currently sits as the worst performer of today on Turkey's main BIST-100 index .XU100
