The United States has announced an increase in its $25m (£20.4m) reward for information leading to the arrest of Venezuelan President Nicolas Maduro on the day he was sworn in for a third six-year term.

The inauguration was overshadowed by accusations from the international community and Venezuelan opposition leaders.

Rewards are also being offered for information leading to the arrest or conviction of Interior Minister Diosdado Cabello.

New incentives of up to $15 million were also offered to Defense Secretary Vladimir Padrino.

Britain also imposed sanctions on 15 senior Venezuelan officials, including judges, members of the security forces and military officials.

The Foreign, Commonwealth and Development Office said those sanctioned were responsible for “undermining democracy, the rule of law and violating human rights”.

Foreign Secretary David Lamy went on to describe Maduro’s regime as “fraudulent.”
