Theresa May should take responsibility if Britain has been too soft on extremists, the leader of Plaid Cymru has said.
Leanne Wood made the comments in a BBC TV debate, which took place a day after the terrorist attack in London.
Ms Wood also said that she would like to see the highest tax rate raised from 45% to 50%.
She said she would be willing to put up taxes to fund public services.
Referring to the prime minister's speech in the wake of the attack, where she said there had been "far too much tolerance of extremism in our country", Ms Wood pointed to the fact that Mrs May had been home secretary for six years prior to being prime minister.
