Tax chief apologises over mistakes
The UK's top tax official has apologised to the 1.4 million people facing an unexpected tax bill.
HM Revenue and Customs Permanent Secretary Dave Hartnett told those who will have to pay an average of £1,428 each he was "deeply sorry".
Earlier Mr Hartnett had told the BBC he "saw no need" to apologise because tax reconciliation was a routine measure.
