A member of the Conservative Party will hold talks today with Sinn Féin chief negotiator Martin McGuinness and a group representing loyalist paramilitaries.
Shadow Northern Ireland secretary David Lidington is expected in the North for separate briefings from the two sides on developments in the peace process.
A Sinn Féin spokesman said: "We will be updating him on the parading situation. . . . maintaining support for the peace process and making people aware of what's happening is vital."
Rioting broke out at a flashpoint Orange Order march in north Belfast last week.
It is understood Mr Lidington will also hold talks with members of the Loyalist Commission, an umbrella organisation set up to defuse tensions among rival Protestant factions.
His trip comes days after a man was shot dead in north Belfast as part of a deepening feud between the Ulster Volunteer Force and the Loyalist Volunteer Force.
