By Matt Chorley, Mailonline Political Editor PUBLISHED: 14:25 EST, 10 October 2013 | UPDATED: 14:37 EST, 10 October 2013 Every Tory man risks appearing sexist, causing harm to the party’s re-election hopes, a senior Conservative MP warned tonight. Bernard Jenkin said even David Cameron was guilty of ‘unconscious slights to women’, including  greeting a leading businesswoman by asking where her husband was. Too often Conservative men think female colleagues can be left to deal with ‘women’s issues’, while ‘men get on with running the country’. Criticism: Tory MP Bernard Jenkin said every man in the party had to change their attitude towards women
