The man accused of murdering Jo Cox sought help for his mental health problems the night before she was killed - but was told to make an appointment and come back the next day.

The disclosure comes as it emerged that Thomas Mair had allegedly bought a number of manuals from an extremist group in the US, which explained how to construct a home-made gun and munitions. There were also reports that police had found ‘Nazi regalia’ at his home.

Mr Mair, 52, visited an alternative therapy centre in Birstall on Wednesday evening, the night before Mrs Cox was killed, where he explained he wanted treatment for depression.

The owner of the Birstall Wellbeing Centre told Mr Mair to return the next day for an appointment but he never went back.
