permanent residence and four year rule?

[Gerry_Marsden]

I have heard that spouses of UK citizens who "have been together for four years or more outside the UK you will be granted indefinite leave to remain (permanent residence) in the UK without having to live in the UK for two years."

My wife (a Russian citizen) and I (a UK subject) have been married for 6 years, 4 of which we have spent outside of the UK (although not all at one time), and 2 of which we spent living in the UK with my wife on a two year wife visa. We are now living in Russia but are hoping to return to the UK next year to settle there permanently.

Based on the info above, does anyone know if my wife would qualify for ILR, or would we have to apply for a two year wife visa again?

Thanks for any help!
