i left barclays in 2013, shortly after bob diamond let the organisation, and it started to change but learned at ba rclays, the skill set i'd learned at barclays, the the skill set i'd learned at ba rclays, the financial analysis skills with something that was outright positive for climate and society and when ijoined wellington management i had never heard of impact investing, it was a new part of the industry and still is today but as soon as i heard about what it was, i knewl but as soon as i heard about what it was, i knew i was going to spend the next few decades working in that pa rt of next few decades working in that part of the industry. we are out of time but thank you so much. thank you. in a moment we'll run through some viewer responses to our twitter question. but first patek philippe is one of the few luxury brands that's still family owned. the 180—year—old company also makes some of the priciest watches on the market. sharanjit leyl spoke to the fourth generation president thierry stern and asked if he'd consider selling the business. iam not i am not willing to sell,
