Marie Stopes International performed 5, 992 terminations in January, the biggest number for a single month in the charity’s 32-year history. MAI blamed excessive boozing in the party season, while British Pregnancy Advisory Service said it was a treatment bottleneck caused by NHS cutback. BPAS think the increased figures may reflect a difficult struggle to access proper services, rather than the results of being careless after drinking. NHS provision ranges from more than 90% of local demand to less than 60% in some areas (NHS website). MSI carried out one third terminations accounting for more abortions in this country than it did before. Therefore, the total number of abortion may not significantly increase insides and outsides NHS.
They two explanations are all possible and lack of evidences. The first explanation could be illuminated by the following causal-effect diagram:

We admit that during the festive season, there were much more parties and more drinking. It’s very likely there were more people times got drunk.
There is certain relationship between alcohol use and risky sexual behavior. However, accurately describing this relationship is very difficult.

• Every year, around 180,000 abortions take place in England (Abortion Rights’s Report Autumn2006).
  In the UK, the law makes it legal to have an abortion in the first 24 weeks of pregnancy providing certain criteria are met. For more information on Laws and Ethics on Abortion, visit Abortion Rights.  
  The law also states that:
  
•   *Abortions must be carried out in a hospital or licensed clinic.
  
•   *Two doctors must agree that the requirements of the Abortion Act 1967 have been met.
  
• In England, nearly a quarter of women pay for their abortions because NHS services are restricts. Almost 90% of abortions take place in the first 12 weeks of pregnancy. Surgical abortion up to 12-week non-anaesthetic charged by MAI is about 550 pounds.
