File on 4 Investigates how Immigration Enforcement officers are tackling sham marriages. Claire Jones follows Home Office officials as they apprehend people entering into, and organising fake marriages in order to circumvent the UK’s immigration laws. She discovers details of criminal gangs charging people up to £30,000 for a partner and 'marriage pack', a set of photos and documents designed to create a convincing back story of the fake relationship. After File on 4 Investigates asked the Home Office why more statistics are not available on suspected fake marriages, they have now committed to regularly publishing these numbers 'in due course'.
