In September/October 2010, Tom Blenkinsop signed Early Day Motions 707: Government Funding for UK Science, and 767: Science is Vital Campaign. Both motions supported investment in science in the face of cuts anticipated in the coalition government's forthcoming spending review.
In February 2015 Tom Blenkinsop voted in favour of allowing mitochondrial donation, which would allow women who carried mitochondrial diseases to give birth to children who would not inherit the disease. An October 2014 briefing report by the Human Fertilisation and Embryology Authority (HFEA), which had been investigating the issue for three years, stated that there was no evidence to show that mitochondrial donation was unsafe. However, some religious groups had said that such procedures should not be allowed. After clearing both Houses, mitochondrial donation is now legal, regulated by the HFEA.
