Monckton joined the UK Independence Party (UKIP) in 2009 and became its chief spokesperson on climate change.[32][33] At the 2010 general election he was nominated as the UKIP candidate for the Scottish constituency of Perth and North Perthshire; although a hereditary peer, he was entitled to stand for election for the House of Commons as he is not a member of the House of Lords. He subsequently withdrew in accordance with UKIP's policy of not opposing other Eurosceptic parliamentary candidates.[34] In June 2010, UKIP announced he had been appointed its deputy leader, to serve alongside David Campbell Bannerman[35] under party leader The Lord Pearson of Rannoch, who owns an estate in Scotland adjoining Monckton's.[36] He was succeeded in the role of deputy leader by Paul Nuttall in November 2010.[37]
In 2011 he stood as lead party-list candidate for UKIP in the Scottish Parliament constituency of Mid Scotland and Fife[38] but did not gain election, with the UKIP list coming seventh after scoring 1.1% of the region's vote.[39] Monckton also headed UKIP's policy unit for a while but according to the party's spokesman he had relinquished any formal role by June 2012, moving into a "semi-detached" relationship with UKIP.[36] By January 2013 he had become UKIP's president in Scotland[40] but was sacked by UKIP leader Nigel Farage in November 2013 following factional infighting.[41]

so, yeah, many of them are deniers.
The success of Ukip in the local and European elections should bring greater scrutiny of its policies, particularly on energy, ahead of next years general election. While the party capitalised on concerns about immigration and the EU in order to gain MEPs and councillors in many parts of the country, its manifestos also outlined energy policies that reflect an outright denial of man-made climate change.
The Ukip European manifesto attacked EU targets for renewables and efforts to close the most polluting coal-fired power plants, on the grounds that they increase the "risk of blackouts", but also promised to scrap the UKs targets for reducing greenhouse gas emissions and to reduce fuel duty on petrol. The partys manifesto for the English local elections offered fewer pledges on energy, but vowed to "end wasteful EU and UK subsidies to 'renewable energy scams,' such as wind turbines and solar farms."
These commitments were very loosely based on Ukip's energy policy pamphlet, which now lies relatively hidden on the partys website after its publication earlier this year. The pamphlet complains of policies that are "dictated by Brussels," but also lashes out at domestic measures, suggesting we should abandon renewables and instead "base our energy strategy on gas, nuclear and coal."
Most strikingly of all, it recommends "a re-think" to allow the UK to exploit its remaining coal reserves, claiming that the local impacts of mining can be avoided by "emerging technologies enabling energy to be recovered from coal by underground combustion". But it fails to admit that although underground coal gasification has been the subject of research for many years, it is still far from being proven as a widespread commercially viable technology.
