TQOTW: DEEMED DOMICILE & AUTOMATIC REMITTANCE

My client is a long-term resident of the UK for tax purposes. However, she is non-domiciled and has been using the remittance basis for her foreign income as it is below £2,000. As she will now have been here for 15 of the previous 20 tax years, will she be caught by the Deemed Domicile rules?
