PM has 'long-term ambition' to abolish national insurance
Rishi Sunak said NI led to a "double taxation" and it would be his aim for it to go in the next Parliament if he won the election.
He described the tax and NI combination was both "unnecessarily complicated" and "unfair".
A day after a 2% cut in the payments made by those in work, the PM told broadcasters of his "long-term ambition" to abolish NI.
