David Cameron: Financial consequences for G4S

David Cameron has said that there may be financial consequences for the security firm G4S, after it failed to fulfil its contract for the London 2012 Olympics.

Speaking in Kabul, he said ''contracts that are not fulfilled will have consequences - including pretty tough financial consequences''.

The Commons Public Accounts Committee says the security firm, whose staff shortages have seen an extra 3,500 soldiers drafted in, should be fined.
