The Home Office will have the power to delay a marriage for a further 70 days while they make appropriate inquiries.
Immigration and security minister James Brokenshire told the Guardian “As of today, marriage can no longer be seen as a ‘fast-track option’ for those seeking to abuse marriage to cheat their way into the UK.”
When the government proposed changes in 2013 in an attempt to crack down of sham marriages it said : "Sham marriages (or marriages of convenience) and sham civil partnerships–where the marriage or civil partnership is contracted for immigration advantage by a couple who are not in a genuine relationship –pose a significant threat to UK immigration control. The Home Office estimates that 4,000 to 10,000 applications a year to stay in the UK, under the Immigration Rules or under the Immigration (European Economic Area) Regulations 2006,are made on the basis of a sham marriage or civil partnership."
Their figures may or may not only be the tip of the iceberg.
