CMS Cameron McKenna has scooped work advising the Department of Transport on the Crossrail project to link east and west London.
The firm beat off competition from Linklaters and four other City firms to win the mandate to provide commercial and corporate law advice to the Government on the consultation process into how the £10bn project should be funded.
However, it is understood that this appointment will not guarantee further work for Camerons once the project moves to the implementation phase.
It is hoped that between £2bn and £3bn will be raised from businesses and the same amount from taxpayers, with the rest being raised by the Government through capital markets - although the total cost could rise to £15bn.
A spokesman for the Department of Transport said: "CMS Cameron McKenna has been appointed to provide advice on private law issues. The Department of Transport lawyers will advise on public law issues. The appointment of Cameron McKenna was in accordance with the applicable rules. It met the key criterion, which was the most economically advantageous tender."
The Camerons team will be led by energy, construction and projects partner Jonathan Beckitt, with assistance from project finance partner Andrew Ivison. Linklaters declined to comment.
"Six months of navel gazing have produced the following startling conclusion at Taylor Wessing: change nothing. Well, as they might say, if it ain't broke, etc. But Taylor Wessing has got itself into a bit of a bind with its tech-firm branding. What was a lovely little unique selling point four years ago has hampered the firm's development in other areas." 12 November
"It's always the quiet ones you have to watch. After 10 years in Germany, Cleary Gottlieb Steen & Hamilton has not only scooped one of the country's pre-eminent antitrust partners, Linklaters Oppenhoff & Rädler's Dirk Schroeder, but has also decided to open a second office in Cologne." 5 November
" What's going on at Manches? The Lawyer is having a hard time keeping track of how many heads of department the firm lost this year, and lost count of the number of partner departures ages ago (although we reckon it's three group heads and around 12 partners in the past 18 months)." 22 October
"More pins in maps: there's something about DLA's frenetic international transformation that is starting to ring warning bells. You can't help wondering whether Nigel Knowles's shuttle diplomacy is verging on the obsessive (all that discipline, all those targets - soooo New Labour)." 1 October
