SIG, the UK insulations specialist, has appointed Panmure, the UK arm of Germany's WestLB, as a joint corporate broker, providing a boost to the bank which downsized its equity operations earlier this year.

Panmure will be joint broker to SIG alongside Cazenove. David Williams, chief executive of SIG, said: "We decided we wanted to strengthen our representation and on balance Panmure were the best people to do that particular job."
