After days of uncertainty and a reshuffle that dragged on for 36 hours, Jeremy Corbyn has installed a new Shadow Defence Secretary to bolster his front bench team.
Gone is Maria Eagle - who backs a replacement for Trident and voted against her leader over airstrikes in Syria - to be replaced with Emily Thornberry.
On the issue of Britain's nuclear deterrent and its successor, Emily Thornberry has consistently either voted against or chosen to be absent from the debate - leaving one such parliamentary session in 2007 to address a CND rally outside the Commons.
In September 2015 she told the BBC that "I don't think being against nuclear weapons is that zany."
With Maria Eagle ousted as co-covener of the Labour Party's own defence review, Mrs Thornberry is unlikely to clash with her colleague Ken Livingstone who is himself an opponent of a nuclear deterrent.
She says she was against the 2003 invasion of Iraq but supported the initial airstrikes against Islamic State in the country because "we have a responsibility for what's happened in Iraq and what is essentially a baby democracy."
"It's a very different situation that we're talking about now, they've asked for our help."
In 2006 and 2007 Emily Thornberry was respectively absent and voted against an inquiry into the Iraq War.
She has also consistently voted in favour of strengthening the military covenant.
Her appointment to the defence job will be seen by many as controversial and marks a return to the shadow cabinet after being forced to resign while working under Ed Miliband.
Then the Shadow Attorney General, she had tweeted a picture of a white van parked on the driveway of a house adorned with St George's flags - an action at the time judged to be mocking and snobbish.

It comes as Shadow Foreign Secretary Hilary Benn denies being "muzzled" after surviving the reshuffle.
