Outsourcing group Serco is heading the FTSE 100 risers following reports it had won a contract from the US department of health worth up to $1.25bn (£820m).
The deal to handle applications for health plans, medicaid and other insurance programmes was said to be worth $114m in the first year, but with four optional 12 month extensions and other projects involved, the total rises to the $1.25bn figure, according to a federal contracting website.
Serco, which receives around 16% of its revenues from the US, is up 36.5p to 661.5p.
