According to Credit Suisse, Temasek has been trying to shift away from financials towards commodities and other sectors, while at Standard Chartered's annual general meeting this year they did not support the elections of all the executive directors; given the prominence of the stake for Temasek this could be interpreted as a negative indicator of their expectations for the group.Engineering group Weir was also the subject of some mergers & acquisitions (M&A) speculation, with Oriel Securities putting US industrial holdings company General Electric in the frame as a possible buyer. Diageo was wanted after it confirmed it is in talks about taking a stake in Indian rival United Spirits.Carnival on an even keelCarnival was buoyant after an admittedly mixed trading update. The cruise operator, still trying to recover from the reputational damage caused by the sinking of the Costa Concordia sinking in January, posted a year-on-year decline in net revenue yields for the third quarter to the end of August despite continuing strength in fleet-wide booking volumes and pricing trends since June. The firm has had to cut prices to get people back on board with the idea of cruise holidays. Third quarter income before taxes was flat year-on-year at $1,336m but ahead of expectations. Cash-strapped travel group Thomas Cook Group has agreed to sell and lease back an office property in Belgium to Koramic Real Estate.

The FTSE 250 miner said its former Chief Executive Officer (CEO) had resigned from his current role as non-executive director following the launch of a probe into 'irregularities' at its Indonesian business. The firm said Ari Hudaya, who was CEO until March and is also president director of PT Bumi Resources, the focus of the investigation, had resigned from the board with immediate effect. The "urgent" probe into PT Bumi Resources, in which the company has a 29% interest, is focusing on the firm's development funds Elsewhere in the sector, Xstrata announced production had begun ahead of schedule at its Lady Loretta zinc mine in north-west Queensland, Australia. The mine was originally supposed to start production at the end of 2013, but first deliveries of zinc-lead-silver ore to the company's Mount Isa processing plant are now set to begin later this month. Commodities trader Glencore International scrapped its previous plans to increase its stake in Kazzinc, the Kazakhstan zinc producer, and came up with a new one which will see the cash component of the transaction lowered.Verny Capital has agreed to sell Glencore an 18.91% stake in Kazzinc, which will increase Glencore's holding to 69.81%.
