He said he would be “swift” but not “hasty” in appointing a new minister.
“As I listened to the evidence around the Causeway it became clear to me that the evidence base was not made out.”
Burrows refused to talk about possible new ministers but said he would “make that decision overnight” and, was asked if he has ruled himself out for the health brief, which he refused to do.
“You will find out like ever other journalist and the public when we announce who the new health minister will be. I’m not going to speculate,” he answered.
He also said that he is willing to speak to Nesbitt “one on one”.
The UUP leader said his party was one that is “going through change”.
“I said that on day one, things are going to change, we need to reconnect with the public.”
“This place has failed to deliver for the people of Northern Ireland,” he said, adding: “We need a circuit break in our politics.”
“The relentless focus of my party and the health minister will be in slashing the access times to the NHS,” he said.
Another ex-leader Doug Beattie quit the UUP in May, lashing out at Burrows’ leadership.
It is unclear whether Nesbitt will follow suit and quit the party as well as resigning his ministry.
