HK to tighten checks on mainland mums

Hong Kong is to tighten up the scrutiny of certificates which mainland mothers-to-be need in order to give birth in the city's hospitals as the controversy continues over pressure on maternity units.

In a related move, health chiefs will also set up a working group to carry out audits of all obstetric units to determine the number of births the city can handle each year.
