In October 2013, Lewis was moved in a Shadow Cabinet reshuffle from the International Development portfolio to the Shadow Northern Ireland one. However, despite his reshuffle, which was seen by many commentators as a demotion, he fulfilled a standing commitment to outline Labour's vision on International Development at The University of Manchester, during Manchester Policy Week. In the September 2015 Labour shadow cabinet reshuffle under the newly elected leader Jeremy Corbyn, Lewis offered to continue in the role of Shadow Secretary of State for Northern Ireland temporarily amid the troubling political situation there. Corbyn rejected his offer and sacked him by text message.
