It is not an easily ascertainable figure. The proposals that we are discussing will enable us to investigate more cases. We have made assumptions based on marriage registration statistics, the volume of reports of suspected sham cases from registrars and feedback from immigration caseworkers who deal with applications that are made on the basis of marriage or civil partnership. The resulting estimate was that between 4,000 and 10,000 applications a year are made to the Home Office on the basis of a sham marriage or civil partnership. My hon. Friend will see from the breadth of the estimate that we need to approach the matter with caution, but it does give a guide to the potential scale of the abuse. There are details in the explanatory paper that we have published on part 4 of the Bill. I expect these provisions to give us a greater ability to identify cases, and therefore to ascertain the number of them.
I apologise to the House, because I was getting ahead of myself in setting out my new clauses. New clause 12 relates to fees. I will come on to the new clause that relates to the deprivation of citizenship afterwards. On fees, we remain committed to ensuring that the UK continues to attract tourists and the brightest and best migrants, including those who are considered to be commercially important to the UK. To ensure that we can do that, it is important that our immigration and visa services are a match for or better than those provided anywhere else in the world.
In a number of important respects, our visa services are already world class. We have expanded and improved the network of visa application centres. There are now 200 around the world, with 12 in each of India and China compared to the three or four that are on offer from most of our competitors. We have introduced online application and booking systems, and 95% of applications are now submitted online. Online applications are supported by translated help text and extensive web guidance. We have also established a business network with dedicated UK visa staff to assist businesses with their visa requirements. All of that is in line with our desire to attract the brightest and best to the UK.
