UK prime minister Tony Blair is set to announce today that the battle against the foot and mouth virus is nearly over. The announcement will come during Downing Street's first formal press conference on the crisis, which will see Blair joined by agriculture minister Nick Brown, chief vet Jim Scudamore and chief scientific adviser Professor David King. Blair is expected to say: ""It is clear that we are winning the battle against foot-and-mouth. We have the right policy. It is working." It is also thought that he will comment on the effective control of the disease, which has been better handled than in 1967.
