A celebrated composer who contracted HIV and hepatitis C through infected NHS blood transfusions will learn the outcome of his legal challenge over compensation payments on Friday.

Andrew March, 36, a haemophiliac from Kensington, west London, was exposed to the viruses when he was just nine years old.

He wants a judicial review of the government’s 2009 decision not to fully implement the recommendations of the Archer report on contaminated blood.

Then health secretary Alan Johnson refused to assess compensation claims on the same basis as in the Republic of Ireland, arguing the UK’s National Blood Service was not at fault - unlike its Irish counterpart.

Counsel Michael Fordham QC claimed the decision had been made for made for manifestly bad reasons.

He said: “The secretary of state should reconsider this important aspect on a correct basis.”

The government claims to have paid out £142m to those infected through NHS blood.
