Footsie gave up a brief rally to close in the red on an uncertain day's trading in the wake of Federal Reserve chairman Ben Bernanke's nervous comments on US economic prospects yesterday. Shares in the US moved lower despite having rallied earlier.Similar sentiments to those expressed by Bernanke appeared in minutes released by the Bank of England today from its Monetary Policy Committee (MPC) meeting earlier this month. The MPC voted 8-1 in favour of keeping interest rates at a record low of 0.5%. Andrew Sentence, who repeated his call for a 25 basis point rate rise, said that the rebound in domestic demand over the past year suggested that the recovery would have sufficient momentum to withstand fiscal tightening, but other MPC members have become concerned about economic prospects.Mining stocks moved ahead industrial metal miners such as Antofagasta, Kazakhmys and Rio Tinto overtaking gold miners such as African Barrick, Fresnillo, and Randgold, which raced ahead in the morning session as the price of gold hit a new high.

IMPs expects net revenues to be up around 3% in the year to 30 September compared with a 4% gain to £3.4bn for the six months to 31 March. Stockbroker Killik & Co was singing IMPs' praises as "one of the most attractively rated defensive companies in the market" with a little bit of added spice of murmurings of bid interest, though given the level of debt IMPs has and the regulatory hurdles any bidder would have to clear, the broker considers the prospect of a bid to be low.Broker comment was less helpful to pumps maker Weir , just a couple of days after it made it into the FTSE 100.
