Former DUP leader Peter Robinson Queen's University speech - Sinn Fein MLA @conormurphysf reacts to what the former First Minister had to say about collapse of Stormont talks in February

"If you want support, you must not show any uncertainty. You must take ownership of the deal." A key line from Peter Robinson's lecture at Queen's University last night. The former DUP leader - now an Honorary Professor in Peace Studies - had a lot to say about leadership and the collapse of talks at Stormont in February. Some observers think his speech contained a thinly veiled attack on his successor Arlene Foster - something Peter Robinson denies. Stephen got reaction from Sinn Fein MLA Conor Murphy and BBC NI political editor Mark Devenport.
