ITV has released the first trailer for the eagerly anticipated fifth series of Downton Abbey, which will be on screen in the autumn.



It may only be 20 seconds long, but it suggests that the new series will see dramatic changes.



Series five will feature a string of top name guest stars including The Royle Family’s Sue Johnston as Denker, Lady’s Maid to the Dowager Countess.



Meanwhile, Dame Harriet Walker reprises her role as Lady Shackleton and Peter Egan returns as Lord Flintshire.
