Chancellor George Osborne has said the 'sugar tax' outlined in his Budget yesterday is a "landmark public health decision".
Speaking on Good Morning Britain, Mr Osborne insisted that the measure would be beneficial for the next generation.
He added that introducing the tax was "the right thing" to try to address the issue of childhood obesity.
Addressing widespread concerns about significant cuts to Personal Independence Payments for an estimated 200,000 disabled people, Mr Osborne claimed that the government would actually be providing more support for disabled people in the future.
He said the Budget was aimed at keeping the welfare system "affordable and sustainable" and helping those who are most in need.
