Mc Guinness quitting Westminister to concentrate on Stormont

Martin McGuinness says he's quitting as a Member of Parliament in London to concentrate on his role as Deputy First Minister in Stormont.

And Sinn Fein says four of its MLA's will leave the Assembly, so they can focus on their jobs in Westminster.

It's part of the party's commitment to end so-called double jobbing where a person holds more than one elected position.

Mr. McGuinness says he will continue to represent his Mid Ulster constituency............
