Latest rumour is that Abellio were preferred bidder, with FirstGroup second. However, following Brexit there is a deal of uncertainty, not least about the price of rolling stock from Alstom. No bidder is going to confirm their bid in these circumstances, given that the risks all lie with them.
DfT are now stuck between the rock of July 21 parliamentary recess and the hard place of a 15 October franchise end date. The smart money has to be on some sort of Direct Award to Abellio, while DfT sort the mess out. I'm not hearing any rumours that DoR has been put on standby.
