BNP Paribas and UBS, advisers to Saint-Gobain on its £3.9bn (€5.7bn) acquisition of BPB, are reported to have been left off the banking line-up for the French building materials maker's latest deal.

Saint Gobain, which agreed an all-cash deal for UK rival BPB this month, has appointed Lazard to sell at least one of its packaging businesses, Reuters reports, citing unnamed sources familiar with the situation.
