Lisa....
Second eldest of Dave's and Maeve's 'known' offspring. Married to Liam, two grown-up daughters Cassandra and Erica.
Lives in rural Essex in a renovated farmhouse with several acres of land. Nearby neighbours are celebrities, minor dignitaries, eminent MP's. Living above her station, common as muck. Nasty and conniving. She has severe mood swings and suffers from anxiety attacks which happen frequently.
Lisa doesn't really like her daughters (or her husband) and just 'puts up' with them. There are frequent arguments at home, usually culminating in Lisa throwing one or both daughters out. However, Liam always smooths it over and they are back in no time.
She harbours deep resentment towards Liam and Liam's family members.
