Sacked deputy prime minister Anwar Ibrahim intends to set off on his delayed nationwide tour tonight after being assured by Prime Minister Mahathir Mohamad he would not be arrested for the time being. Since his unceremonious sacking last week, Mr Anwar has not ventured further from his home in Bukit Damansara than the mosque at the end of his street. His two earlier attempts at travelling cross-country to rally support were called off after private warnings from authorities. Mr Anwar said he wanted to attend an Islamic class he had been invited to by a top scholar tonight in Kajang, an hour's drive south of the capital. He then hoped to head north to his constituency of Penang tomorrow. Meanwhile, police have seized tapes of Mr Anwar's speeches and leaflets that supporters have been distributing. One prominent supporter, ruling United Malays National Organisation party youth wing leader Ahmad Zahid Hamidi, refused a demand he quit his post. Dr Mahathir said UMNO could afford to let go those party leaders backing Mr Anwar.
