Furlough and maternity leave

We have a member of staff who has  been in her current role for 1.5 years and is expecting a baby in September. She qualifies for the full maternity package offered  (18 weeks full pay, then Statutory Maternity Pay for a further 21 weeks). 

We are now considering placing this staff member on furlough

Could this affect her maternity leave and pay, which will start in early September. The usual criteria for Statutory Maternity Pay, is that you have to have worked for your employer continuously for at least 41 weeks before the expected week of childbirth, earning on average at least £118 per week. 
Would she still be counted as "employed" during the period of furlough, would the income from the government furlough scheme be counted as "earnings"
Many thanks for any advice you can offer;
