A man who abused a Tory MP in a crude email after the politician was headbutted by a rival was fined £110 and ordered to pay costs of £100.
Nicholas Scales told MP Stuart Andrew he should "stop wasting police time and get your f****** job done", Leeds Magistrates Court heard.
Scales had pleaded guilty last month to sending a malicious communication after the Labour MP Eric Joyce attacked Mr Andrew in the House of Commons in February,
The court heard how Scales, 41, of Upper Hale Road, Farnham, Surrey, sent the email to Mr Andrew's constituency office in Leeds and it was read by a secretary.
The rant continued, saying if the MP had ever been out in Leeds or Bradford he would have known how to defend himself, and called Mr Andrew a "queer mammy's boy".
