Mr Newmark served on the Science and Technology Select Committee (2005–7).
Mr Newmark graduated from Harvard College, receiving a BA in History in 1980. He was a Research Graduate in Politics at Worcester College, Oxford from 1980-2, and received an MBA in Finance from Harvard Business School in 1984. He was Vice President in the International Division of Shearson Lehman Brothers from 1984-7, a Managing Director of Newmark Brothers Ltd, a corporate finance advisory company from 1988-93, and then a Director of Stellican Ltd from 1993-98. From 1998-2005, Mr Newmark was a Senior Partner at Apollo Management (UK) LP, a leading International Private Equity firm.
Mr Newmark contested Newcastle Central in 1997, and Braintree in 2001. He was elected as the Member of Parliament for Braintree (in mid Essex) in the 2005 General Election over Labour incumbent Alan Hurst.
In May 2008 in the abortion amendments to the Human Fertilisation and Embryology Bill (now Act), Brooks Newmark voted for the abortion time limit to be lowered to 20 weeks against scientific and medical consensus which is currently 24 weeks. After four separate parliamentary votes on varying time limits, the majority of MPs voted to keep the abortion time limit at 24 weeks, in keeping with scientific and medical consensus, hence no abortion amendments were added to the bill.
In September 2011 Brooks Newmark voted for Nadine Dorries's amendment to the Health and Social Care Bill, 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 Brooks Newmark 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.
In 2009, Mr Newmark introduced a Private Members Bill, Cervical Cancer (Minimum Age for Screening), to reduce the age for cervical cancer screening to 20. The bill came on the back of a petition and campaign by The Sun newspaper, which was inspired by Jade Goody’s death at 28 from cervical cancer. According to Mr Newmark, "Cervical cancer may be rare in women under 25, but it is inexcusable to dismiss the cases that occur as negligible statistics."
In August 2009 the British Medical Journal published a large study examining the screening age for cervical cancer. It found that screening was associated with an 80% reduction at age 64, 60% at age 40, and so on. But cervical screening in women aged 20-24 has little or no impact on rates of invasive cervical cancer in the following 5 years. Liberal Democrat MP Evan Harris introduced these findings to the debate and responded to Mr Newmark with the words, "The hon. Member for Braintree cited evidence from The Sun, so I want to refer to a recent edition of the British Medical Journal".
Faith based Adoption Agencies
In 2007, Brooks Newmark seconded Early Day Motion 742 calling on the government to exclude "faith based" adoption agencies from the Equality Act to avoid such agencies being forced to consider gay couples.
