British lawmakers of Pakistani origin hit out at President Asif Ali Zardari on Tuesday, saying he should be back home sorting out the flooding disaster rather than launching his son's career. Some ethnic Pakistani politicians have pulled out of a planned meeting with Zardari, insisting he should abandon his visit to Britain to head up Islamabad's response to the devastating floods. Zardari starts his five-day visit later Tuesday. Alongside talks with Prime Minister David Cameron, Zardari was to meet with Pakistani-origin lawmakers, and attend an event Saturday which reports say is primarily to launch the political career of his son Bilawal Bhutto Zardari. The 21-year-old is the son of Zardari and former prime minister Benazir Bhutto. He is co-chairman of the Pakistan Peoples Party alongside his father and has been studying at Britain's Oxford University.
