BRITAIN will be “fit to fight” under Labour, party leader Sir Keir Starmer said today in a renewed commitment to militarism.

The Labour leader also toughened up his commitment to spending far more on arms, saying that under Labour the military budget would aim to reach 2.5 per cent of gross domestic product “as soon as possible.”

And he both pledged to keep the Trident nuclear weapons system, building four new nuclear-armed submarines with one always ready to launch missiles, and that he would be ready as prime minister to use it.
