I have hugely enjoyed my time as Shadow Secretary of State for Defence.back
Labour has a strong foundation in defence with policies to be proud of and built upon.
Labour's campaigning to support veterans and our Forces, through measures such as the Veterans' Interview Programme guaranteeing service leavers job interviews, shows how much we value those who serve and have worked to give them greater opportunities.
Our support for a continuous-at-sea deterrent demonstrates our commitment to UK national security.
Labour's advocacy for giving service personnel greater skills combined with our plans to manage the MoD budget show our commitment to defence reform.
The changes we have made to the Party, for example attracting over 800 new military members and creating a new campaigning body, Labour Friends of the Forces, highlight our determination to be a party of and for the Armed Forces.
I would like to thank all who have been in the Shadow Defence Team - Kevan Jones, Gemma Doyle, Alison Seabeck, Russell Brown, Bridget Phillipson, David Hamilton, Michael Dugher, Richard Rosser and Denis Tunnicliffe - for their hard work.
There is an exciting future for Labour and defence, just as there is with international development, which is why I am looking forward to getting on top of my new post and building on the achievements of Ivan Lewis.
I have long argued that the best defence policy is often first class diplomacy or world class development policy. Development is central to our national security as well as upholding our national values of tolerance and justice which transcend our borders. I will work to ensure Labour's position of global leadership in arguing for a progressive, targeted aid policy is maintained, working closely with our international allies and world-leading NGOs.
Labour's history is deeply internationalist and that is where our future lies. I may have changed jobs but l will go about this new role with just as much commitment and energy.
Today I've also spoken with Alistair Darling and I look forward to playing a bigger role in the Better Together campaign.
