The article explains the variation of climate change salience in party manifestos, examining the effects of party characteristics. Creating a novel measure of parties’ climate change salience based on Comparative Manifesto Project data, the article finds that parties have broadly not made climate change a salient issue, though significant differences remain. Left–right ideology significantly helps explain these differences and is more important than any other party characteristic in explaining the variation. This underlines the importance of ideology over economic and policy preferences, size and strategic incentives and incumbency constraints and points towards the partisan (as opposed to the valence) nature of the climate change issue. These results contrast to those of an identical analysis of environmental salience where ideology is found to have no effect, underlining how the two issues should be treated differently and lending further support to the argument that climate change is not a valence issue.

This article examines the potential implications of the United Kingdom's exit from the European Union (so‐called ‘Brexit’) for the success and survival of the country's flagship climate policy, the Climate Change Act 2008. The impact of a ‘soft’ and a ‘hard’ Brexit for the main features of the Climate Change Act are assessed, building on documentary evidence and elite interviews with key policy‐makers and policy‐shapers. The article argues that the long‐term viability of the Climate Change Act was being threatened even before the EU referendum, and that Brexit will do little to improve this situation. Even though the existence of the Climate Change Act is not under immediate threat, a range of issues presented by Brexit risk undermining its successful implementation.

Regulatory governance involves the use of heterogeneous mechanisms to extract welfare gains from market-based processes. While often viewed as a depoliticization mechanism, here, we explore a distinctly political manifestation of regulatory governance. Our study focuses on the governance of affordable housing in England, specifically on local authorities' use of 'Section 106 0 (S106) powers to compel private developers to include affordable housing in new developments. We show that, following the financial crisis, the governance of affordable housing shifted from a partisan to a valence issue. As the crisis increased the issue salience of affordable housing, left-wing authorities' hitherto higher tendency to intervene was eroded in the midst of a broad-based increase in S106 deployment. In addition to extending insights into the political economy of regulatory state intervention, our findings shed valuable light on the undersupply of affordable housing in England.

1. The decision of the UK to leave the EU has far-reaching, and often shared, implications for agriculture and fisheries. To ensure the future sustainability of the UK's agricultural and fisheries systems, we argue that it is essential to grasp the opportunity that Brexit is providing to develop integrated policies that improve the management and protection of the natural environments, upon which these industries rely.2. This article advances a stakeholder informed vision of the future design of UK agriculture and fisheries policies. We assess how currently emerging UK policy will need to be adapted in order to implement this vision. Our starting point is that Brexit provides the opportunity to redesign current unsustainable practices and can, in principle, deliver a sustainable future for agriculture and fisheries.3. Underpinning policies with an ecosystem approach, explicit inclusion of public goods provision and social welfare equity were found to be key provisions for environmental, agricultural and fishery sustainability. Recognition of the needs of, and innovative practices in, the devolved UK nations is also required as the new policy and regulatory landscape is established. 4. Achieving the proposed vision will necessitate drawing on best practice and creating more coherent and integrated food, environment and rural and coastal economic policies. Our findings demonstrate that "bottom-up" and co-production approaches will be key to the development of more environmentally sustainable agriculture and fisheries policies to underpin prosperous livelihoods. 5. However, delivering this vision will involve overcoming significant challenges. The current uncertainty over the nature and timing of the UK's Brexit agreement hinders forward planning and investment while diverting attention away from further in-depth consideration of environmental sustainability. In the face of this uncertainty, much of the UK's new policy on the environment, agriculture and fisheries | 443 People and Nature STEWART ET Al.
