Royal Bank of Scotland is looking at making radical changes to its plan to set up and sell off Williams & Glyn in a bid to accelerate the much-delayed project, with most of the options looking at alternatives to the hugely expensive IT project currently underway – but one potential idea even includes the sale of NatWest. The Sunday Telegraph understands that the bank and its advisers have carried out a series of brainstorming exercises to seek any alternative routes to establish spin off bank W&G, to save time and money on the £1.5bn project and to prove to the European Commission that bosses really have done everything they can to create the new challenger bank quickly. Last month bosses revealed that there is a "significant risk" the new bank will not be independent by the end of 2017, the deadline imposed by the EC after RBS missed the previous target of the end of 2016.
