MPs to get security brief after life-threatening attack

Key points

• Security agencies will brief federal politicians after an alleged attack on independent MP Helen Haines left her in a critical condition. Dr Haines had a leg amputated after she was allegedly hit by a four-wheel drive outside her electorate office in Wangaratta on Monday afternoon.
• The Australian Federal Police have urged the public to reduce heated rhetoric amid a rise in harassment of politicians. Fellow independent Monique Ryan said she had referred two threats against her to police within 24 hours.
• Opposition defence spokesman James Paterson said electorate offices lack adequate protection.
