Malawi poll annulment challenges filed

Malawi's President Peter Mutharika and the country's electoral commission have appealed against a constitutional court decision to annul the results of last year's election. 

Mr Mutharika - who had been declared the winner - says the court's ruling goes against democracy. 

After months of taking evidence, the court this week ordered a new poll, having found widespread irregularities including result sheets with sections blotted out or altered. 

Barely 30% of the results in what some in Malawi are calling "the Tippex election" were verifiable.

It is only the second time a vote has been overturned by the courts in Africa.
