President Jacob Zuma delivers his 2013 state of the nation address.

Cape Town - President Jacob Zuma's state of the nation address covered a wide variety of social issues, but was scant on detail, a sociologist said on Thursday evening.

“The president covered a wide range of ground, but perhaps he lost a bit of focus,” said Prof Roger Southall of the University of the Witwatersrand's sociology department.

He said Zuma mentioned the importance of small business and government support for such entities, but gave “absolutely no details”.

It was promising that Zuma had spoken about renewable energy, but more money should be allocated to realising green initiatives, Southall said. - Sapa
