UK sausage-skin maker Devrp has warned that its full-year operating profit will likely miss forecasts.

The company blamed higher input costs and the negative impact of currency exchange, due to a weak Czech crown.

Nevertheless, the company emphasised that volumes have continued to grow across a number of key markets, including Japan, Europe and the Americas.

The company also unveiled plans to invest GBP35m in increasing capacity and productivity initiatives in 2013 and 2014.
