Commodities trading firm Liberty House has confirmed it will put in a formal bid to buy Tata Steel's UK assets.
The firm, headed by Sanjeev Gupta, was first to express an interest after the Indian conglomerate announced the shock decision to dispose of its loss making UK business, including the country's biggest steel plant at Port Talbot in south Wales.
A spokesman said Liberty is planning to submit a letter of intent to Tata and has put together an internal transaction team and team of external advisers to take the bid forward.
A management buyout team is also planning to submit a bid under the name Excalibur Steel UK Limited.
It has appointed investment banker Mark Rhydderch-Roberts as a non-executive director.
He joins Stuart Wilkie, the head of Tata's United Kingdom strip steel business, former Alcan senior executive and venture capitalist Roger Maggs, Simon Gibson, chief executive officer of Wesley Clover and company secretary Jon Fernandez Lewis in the board.
The Government has pledged to support any buyer of the business by buying up to a quarter stake and making hundreds of millions of pounds of finance available.
Tata has not publicly set a deadline for any deal but has made it clear it cannot sustain the £1m a day losses indefinitely.
A spokesman for Liberty said: "We can confirm that Liberty will submit a letter of intent to Tata Steel today and has put in place a strong internal transaction steering committee and panel of leading external advisers to take the bid forward.
"We hope to make a further short statement later today."
