Where now for the immigration debate?

The coalition's political approach is at risk of unravelling, but genuine policy challenges remain.

The economic impacts of migration, and of immigration policy, are back in the spotlight. Today, Gus O’Donnell accused the government of "shooting itself in the foot" on growth by restricting skilled immigration. Yesterday’s two big economic reports, from Michael Heseltine and the Resolution Foundation’s Commission on Living Standards also considered the issue from different perspectives.

O’Donnell and Heseltine both highlight the potentially negative impacts on growth of immigration policy that restricts (either in principle or in practice) the ability of businesses to access a global pool of talent. Meanwhile, the Commission on Living Standards, in an exhaustive study of the causes of the "wage squeeze" that has affected low and middle earners in the UK, concludes that immigration has not been a significant factor.

So if immigration is important for growth, and doesn’t have significant effects on low and middle earners (the evidence for both these claims is strong), what’s the problem? Why does the government persist with an immigration policy that appears to make no economic sense, and why does the opposition not offer a more straightforward criticism of it? There is sometimes a feeling on the "progressive" side of the argument that this is simply a problem of politics and public opinion – if only the economic evidence could be better communicated and understood, then the path would be clear for a more "rational" (and, by implication, more liberal) immigration policy. This is wrong, for at least two reasons.

The first is that there are genuine policy challenges with respect to immigration policy that need to be addressed – this is not simply a case of politics and public opinion muddying the crystalline waters of economic evidence.

The impacts of migration on the labour market and the economy are complex. Although the finding that migration has had little impact on wages or unemployment is robust, there are some important caveats which need to be considered. Too little is known about the distributional impacts of migration. The Commission on Living Standards is right that even at the bottom end of the labour market, the impacts of migration on wages and employment seem to be very small, but this does not rule out more significant impacts on specific groups of workers (for example in some sectors in particular local areas). Nor does it take into account the fact that migration (including skilled migration) has been part of an economic model that has seen wages at the top end of the labour market become disconnected from those at the bottom. Pleas from the City to be able to bring in more highly-skilled (and highly-paid) migrants may make sense from the point of view of economic growth, but we should take seriously the argument that some kinds of growth are better than others, and that migration policy needs to be part of that discussion.

Migration also poses a range of complex policy challenges beyond labour markets and the economy, particularly at the local level – the rapid population change that can result does affect housing, public services, and community cohesion, whatever the economic benefits.

The second reason, which Heseltine recognised in his report yesterday, is that migration policy must have "public assent". This is not just an argument for better communications. Progressives and economic liberals may find some aspects of public opinion on this issue uncomfortable, and it is always open to them to try to shift the terms of debate – but the right response can never be simply to ignore the views of the electorate. Arguments over migration cannot be left to experts or economists but must be shaped through democratic debate and choice.

So where does this leave migration policy and politics? There are three key challenges that policymakers and politicians must face up to. The first is that migration must be situated in a wider policy debate about the economy (and housing, welfare, and communities). Ed Miliband has understood this, and Labour is showing promising signs of tackling migration policy in this way. The second is that many of the real policy challenges are local ones, and need to be addressed at the local level – something that will require a big change of approach in a policy area that has traditionally been highly centralised. The government’s net migration target is about as far away from the nuanced local policy mix that is needed as it is possible to get. In light of this, the third challenge presents a paradox – although there are real policy challenges at the local level, the public don’t (on the whole) feel that immigration is a problem in their own local communities, although a large majority do feel that it is a problem for the country as a whole.

So politicians are faced with a national political problem which is cast in terms of very simple choices, and a need for nuanced and local policy solutions. The government has opted to play the political game rather than the policy one – a strategy that is at risk of unravelling under the weight of its own contradictions, and the kinds of critiques that have emerged this week. Labour are engaging seriously with the policy questions, but are still in search of a narrative on immigration – "one nation" Labour is as good a starting point as any, but much more work is needed given the party’s difficult recent history on this issue.

Voters are turning against Brexit but the Lib Dems aren't benefiting

Labour's pro-Brexit stance is not preventing it from winning the support of Remainers. Will that change?

More than a year after the UK voted for Brexit, there has been little sign of buyer's remorse. The public, including around a third of Remainers, are largely of the view that the government should "get on with it".

But as real wages are squeezed (owing to the Brexit-linked inflationary spike) there are tentative signs that the mood is changing. In the event of a second referendum, an Opinium/Observer poll found, 47 per cent would vote Remain, compared to 44 per cent for Leave. Support for a repeat vote is also increasing. Forty one per cent of the public now favour a second referendum (with 48 per cent opposed), compared to 33 per cent last December. 

The Liberal Democrats have made halting Brexit their raison d'être. But as public opinion turns, there is no sign they are benefiting. Since the election, Vince Cable's party has yet to exceed single figures in the polls, scoring a lowly 6 per cent in the Opinium survey (down from 7.4 per cent at the election). 

What accounts for this disparity? After their near-extinction in 2015, the Lib Dems remain either toxic or irrelevant to many voters. Labour, by contrast, despite its pro-Brexit stance, has hoovered up Remainers (55 per cent back Jeremy Corbyn's party). 

In some cases, this reflects voters' other priorities. Remainers are prepared to support Labour on account of the party's stances on austerity, housing and education. Corbyn, meanwhile, is a eurosceptic whose internationalism and pro-migration reputation endear him to EU supporters. Other Remainers rewarded Labour MPs who voted against Article 50, rebelling against the leadership's stance. 

But the trend also partly reflects ignorance. By saying little on the subject of Brexit, Corbyn and Labour allowed Remainers to assume the best. Though there is little evidence that voters will abandon Corbyn over his EU stance, the potential exists.

For this reason, the proposal of a new party will continue to recur. By challenging Labour over Brexit, without the toxicity of Lib Dems, it would sharpen the choice before voters. Though it would not win an election, a new party could force Corbyn to soften his stance on Brexit or to offer a second referendum (mirroring Ukip's effect on the Conservatives).

The greatest problem for the project is that it lacks support where it counts: among MPs. For reasons of tribalism and strategy, there is no emergent "Gang of Four" ready to helm a new party. In the absence of a new convulsion, the UK may turn against Brexit without the anti-Brexiteers benefiting.
