South East Labour has issued a statement saying they are saddened and shocked by the news of Del Singh’s death in Kabul.
Del Singh, 39, was a committed campaigner who was described as being passionate about changing lives for the better.
Mr Singh was from the Southampton area and worked as an International Development Specialist.
He had over a decade of experience managing EU and UN projects in post-conflict countries, including Afghanistan, Palestine, Libya and Sierra Leone.
Closer to home the 39-year-old volunteered at two charities that supported homeless people and mentored job seekers.
John Denham MP paid tribute to Mr Singh describing him as an inspirational man:
Del was an inspirational man and simply one of the nicest people you could meet.
Everything he did - delivering development aid in some of the world’s most dangerous places, running a charity marathon in the heat of Gaza, or representing the Labour Party - was driven by a passion to make a real difference to people's lives.
