In May 2008 in the abortion amendments to the Human Fertilisation and Embryology Bill (now Act), David Blunkett voted to keep the current time limit of 24 weeks in line with the scientific and medical consensus.
In October 2010, David Blunkett signed Early Day Motion 767: Science is Vital Campaign. The motion stated that the house "believes that continued investment in research is vital in order to meet the technological and social challenges of the 21st century, and to continue to attract high-tech industries to invest here; further believes that large cuts to science funding are a false economy, due to evidence that research investment fuels economic growth".
As Home Secretary, Mr Blunkett reclassified cannabis from class B to class C, following a recommendation by the Advisory Council on the Misuse of Drugs (this reclassification was reversed by Jacqui Smith). He did not, however reclassify ecstasy from class A to class B as also recommended. A speech from 2002 on this subject: http://www.theyworkforyou.com/debates/?id=2002-07-10.886.0
