Jeremy Corbyn and Theresa May are clashing today at Prime Minister's Questions for the first time since the Carillion collapse.

The pair are likely to trade blows over who is to blame for the firm going into liquidation and putting 20,000 jobs at risk.

And it comes after a union chief said the response for at least 8,500 private sector workers who face losing their jobs today is "wholly inadequate and frankly inept".

GMB union general secretary Tim Roache hit out at advice on the Cabinet Office website.

Under the heading "I’m worried about my job", the website states simply: "JobCentre Plus, through its Rapid Response Service, stands ready to support any employee affected by this announcement."

He said: "What they’ve said is if you haven’t been picked up by another private sector company by close of play today, then here’s the Jobcentre Plus address. That’s frankly scandalous.”
