THE Royal Family has sent invitations for the wedding of Prince William and Kate Middleton to guests by fax. The save-the-date warnings were sent to the major sovereigns in Europe because protocol dictates that they are given earlier notice than foreign heads of state and non-VIP guests. However, the full handwritten invitations, embossed in gold, will be sent to all 1,800 guests by the Lord Chamberlains Office next month. Courtiers told the Daily Mail that this was the most efficient way of passing on information about large-scale events. Some of the guests have already confirmed they will be at Westminster Abbey on April 29. King Constantine, Greeces former monarch, his wife Queen Anne-Marie, 64, and their eldest son Crown Prince Pavlov, 43, are to attend. Crown Prince Alexander of Serbia released a statement on their website to say they were delighted to attend. The monarchies of Romania, Spain, Holland, Norway, Sweden, Denmark and Belgium are also expected to attend. A spokesman for St Jamess Palace aide told the newspaper: The Lord Chamberlains Office does give a heads-up to royal families first, in line with protocol. Telegraph Obese women have more complicated births Overweight pregnant women are more likely to be overdue and have more complicated births, a study has found. Women who were overweight or obese before they conceived were more likely to have a longer pregnancy, need to have labour induced artificially and to go on to require caesarean section births. The research was conducted by a team at Liverpool University who examined the records of almost 30,000 women who gave birth over four years. Three in ten obese women were overdue, defined as still pregnant ten days after their due date, compared with around two in ten of healthy weight women. More than a third of obese women had their labour induced, compared with just over a quarter of normal weight women, the study published in the British Journal of Obstetrics and Gynaecology found. In addition almost three in ten obese women had an induction of labour which later resulted in a caesarean delivery compared to less than two in ten normal weight women. TG However, more than seven in ten obese women still gave birth naturally and the rates of complications in labour and for the baby were the same as in normal weight women. Other studies have found that maternal obesity is now one of the biggest risks in childbirth. In 2007 it was found that half of all women who died during pregnancy or soon after giving birth were overweight. Maternity units have had to order special operating tables, wheelchairs and other equipment to deal with the increasing number of obese mothers and doors have had to be widened to accommodate them. Management of obese prolonged pregnancies is often difficult as induction of labour is associated with a high risk of caesarean section and the possible complications that follow including infection, bleeding and clots.
