Britain’s Prince William has gone on leave from his job as an air ambulance pilot after completing his training early, royal officials said Tuesday, days before the expected birth of his second child. A spokesman for Kensington Palace, William’s official residence, said his next round of training was due to begin on June 1. ‘As he now will not have any further training to complete after returning from paternity leave, he will not return to duties with Bond (his employer) until that time and will remain on unpaid leave until then,’ he said. Prince William’s wife Kate is expecting their second child this month. The boy or girl will be fourth in line to the throne after their first child, Prince George, who was born in 2013. The prince took up his new job in March but will only start flying rescue missions later this year. He is reportedly to be paid an annual salary of £40,000 (55,700 euros, $60,000) but will donate it in full to charity. He is thought to be the first royal directly in line to the throne to work for a civilian employer. Experts say the royal birth could inject tens of millions of pounds (euros, dollars) into the British economy, and a baby princess would give an added boost in the years to come.  ‘If it’s a girl, it’s like an investment that is going to pay off for the media and designers,’ Joshua Bamfield, director of the Centre for Retail Research,
