The Ulster Unionist leader, David Trimble, and the Sinn Fein president, Gerry Adams, will this week visit Downing Street in an attempt to revive the Ulster peace process.

The process has stalled since a breakdown in trust between unionists and republicans over IRA activity.

A source told today's Guardian: "Trust is low on both sides. But people on all sides miss devolution. They can see it is far better for local ministers to deal with domestic issues, rather than the absurdity of having them dealt with by direct rule."
