Your friend may be able to claim jobseekers benefit if they have sufficient RSI contributions - otherwise if they make an application for jobseekers allowance the income of the household ie. income, savings, investments etc of your friend and their partner will be assessed as part of a joint means assessment.
There is a likelihood that they wont qualify for jobseekers allowance because of household means - and if that happens depending on the income of her partner if they are a low income household they should look into claiming Family Income Supplement....
