Libel Law Reform
In March 2010, Lindsay Roy signed Early Day Motion 423 calling for a reform of the English libel law. The motion noted that human rights activists, scientists, writers and journalists are currently prevented from publishing, and the public prevented from reading, matters of strong public interest due to the chilling effect of the law.
Lindsay Roy was a member of the All-Party Parliamentary Group for Integrated Healthcare.
In June 2010, Lindsay Roy signed Early Day Motion 284: BMA Annual Representative Meeting Motions on Homeopathy which expressed concern at a number of motions to be put forward at the British Medical Association's annual representative meeting calling "for no further commissioning of, nor funding for, homeopathic remedies in the NHS", and "thinks that an integrated NHS, which employs the best from the orthodox and complementary ... could deliver better and more cost-effective outcomes at a time of financial prudence".
In October 2010, Lindsay Roy signed Early Day Motion 707: Government Funding for UK Science. The motion stated that the house "supports the view of the President of the Royal Society that short-term austerity risks undermining the UK's future science base", noted that other countries were investing in science to promote economic growth, and "believes that investment in basic scientific research throughout the UK is vital if the commercial benefits of developing new technology are to be broadly spread".
