The right hon. Gentleman draws me on to the e-Borders system and its programme. We hear the point that the Committee have made in respect of that. While valuable, the border systems data are, in our judgment, not the right way to measure immigration flows, for which we believe that well-designed surveys are more appropriate. The data do not capture passengers’ onward travel plans or duration of stay, so they could not be directly used to measure long-term international migration. Rather, they are designed to alert us to passengers of interest leaving and entering the country, so that we can strengthen security and immigration controls. They allow law enforcement partners to target and monitor those seeking to travel to and from the UK who might harm this country’s interests—the point my hon. Friend the Member for Windsor highlighted. They are an extremely valuable tool; indeed, since 2010 our border systems have issued alerts resulting in more than 13,300 arrests, including 60 for murder, 59 for kidnap and 167 for rape.
I therefore understand why the Committee took the view that border systems data might entirely replace the IPS. However, that is at odds with the statistical advice we have received and the evidence that academic experts provided to the Committee. None the less, it is important to see how the information can be used to interpret what is happening. That is why it is important to share Semaphore data with the ONS, so that the ONS can carry out further analysis.
I want to come back on some of the points made about exit checks. The Home Office is on track to meet by April 2015 the commitment to introduce exit checks on those who leave the UK via scheduled international air, sea and rail services. Exit check capability will be
founded on advance passenger information, supplemented by embarkation checks at ports, where necessary. That will further bolster border security.
Exit checks will also identify individuals who are wanted by the police, who pose security, immigration or customs threats, or who fail to comply with the conditions of their visas. It is important that checks are used in that way. We have introduced a power in the Immigration Act 2014 to enable those already involved in outbound passenger processes—for example, the staff of airlines, other carriers and port operators, as well as others—to integrate embarkation checks with existing processes where necessary. There is also a power to compel them to do so, if necessary.
