Britain's Foreign Office today confirmed the death of Dhamender Singh Phangurha, also known as Del Singh.
Singh was a Labour Party candidate from the South East for the European Parliament, BBC reported.
He had previously been an advisor to the European Mission in Kosovo and worked on UN and DFID-funded projects in Afghanistan, Sierra Leone, Libya, Nepal and Palestine.
Labour Party leader Ed Miliband said Singh, who had "dedicated his life to working with people across the world who needed his support", was killed in a "barbarous act of terror".

The attack occurred last evening when a bomber blew himself up outside the heavily-fortified Taverna du Liban restaurant in the upmarket neighbourhood of Wazir Akbar Khan.
Two gunmen then entered the restaurant and started "indiscriminately killing" people inside, Deputy Interior Minister Mohammad Ayoub Salangi said. The attackers were eventually shot dead by security forces.
Two Americans, two Britons, two Canadians, a senior International Monetary Fund representative from Lebanon and the restaurant's Lebanese owner were among the dead. Salangi said five women were among the dead.
The Taliban claimed responsibility for the attack, saying it targeted foreign officials.
