The health of Pakistan's jailed former premier Nawaz Sharif has deteriorated, his daughter claimed on Friday, alleging that authorities are not letting his cardiologists examine him at the Lahore jail.

Maryam Nawaz said that Sharif, who has been serving a seven-year jail term in Lahore's Kot Lakhpat jail in the Al-Azizia Steel Mills corruption case, is suffering from a pain in his arm, "which is most likely to be angina".
