The Labour MP for Derby North, Chris Williamson, has criticised the decision to award the £1.6bn Thameslink contract to Siemens.
On his Twitter account, Mr. Williamson said:
The Department for Transport has confirmed that Bombardier has lost out on the £1.6bn contract to Siemens.
It also confirmed the deal is in the Alcatel standstill period and will not be formally announced for ten days.
Bombardier will not be confirmed as losing the Thameslink contract for another ten days according to reports.
German firm Siemens will only then be confirmed as the winners of the contract due to a legal requirement known as the Alcatel standstill period.
This allows time for unsuccessful bidders to challenge the decision.
There are reports that Derby-based company Bombardier has lost out on the £1.6bn Thameslink contract putting jobs under threat.
Around 1,400 jobs have already been lost since German firm Siemens was originally announced as the preferred bidder to provide the 1,200 carriages two years ago.
