The future of troubled engineering firm Carillion is being discussed at high-level government meetings this weekend, the BBC understands.
The firm is a key government contractor for projects including the HS2 high speed rail scheme, schools and prisons.
There are fears it is close to collapse as it struggles with £1.5bn of debt and a pension shortfall of £587m.
On Friday, Carillion said it remained in constructive dialogue about short-term financing.
Reports that creditors had turned down a potential rescue plan sent the firm’s shares down by more than 28% on Friday.
