A Catholic peer met Syrian president Bashar al-Assad in Damascus this week.
Crossbench peer Lord Hylton was part of a contingent including Baroness Cox, Bishop Michael Nazir-Ali, former Anglican Bishop of Rochester, and vicar Reverend Andrew Ashdown.
The contingent faced criticism for meeting the Syrian leader.
After the office of the Syrian Presidency shared a photograph of the meeting on social media, Labour MP John Woodcock, vice-president of the All Party Parliamentary Group (APPG) on Syria, said: "Whatever good intentions this British delegation has will fail; their presence at this man's side can only strengthen him as his campaign of terror continues.”
