Two cousins of a British man facing execution in China are travelling to the country to make a last ditch appeal for mercy. Akmal Shaikh, 53, from London, is due to be executed on Tuesday next after he was convicted of smuggling heroin. But the relatives of the man plan to deliver a plea on his behalf to President Hu Jintao. Mr Shaikh's supporters say he is mentally ill and British Prime Minister Gordon Brown has asked Chinese authorities for clemency. British consular staff have also flown to the Chinese region of Xinjiang to see the condemned Briton and discuss his case with local officials.<br/>
