Zimbabwe's presidential spokesman says former leader Robert Mugabe and his wife, Grace, have traveled to Singapore on their first trip abroad since Mugabe resigned last month under pressure from the military and ruling party.

Press secretary George Charamba confirms that the 93-year-old Mugabe has gone on his annual leave and for regular medical checkups. He says Mugabe is free to travel when and where he wants.

Mugabe has not made any public appearances since he stepped down after 37 years in power.

For many years he has taken annual trips to Singapore and other Asian countries in January and February.
