In June 2010, Jessica Lee signed Early Day Motions 284: BMA Annual Representative Meeting Motions on Homeopathy, 285: Effect of Homeopathic Remedies on Breast Cancer Cells, 286: Homeopathic Medicines in the Treatment of Moderate to Severe Depression, and 287: Homeopathy and Chronic Primary Insomnia. However she later withdrew her signature from all four EDMs.
Ms Lee voted for Nadine Dorries’s amendment to the Health and Social Care Bill on 7 September 2011, which was ultimately defeated by 368 to 118 votes. This amendment would have stopped BPAS and Marie Stopes from providing counselling for women with unwanted pregnancies and allowed ‘independent’ counselling including that provided by faith-based organisations.
In February 2015 Jessica Lee 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.
