Back in October, despite being deducted a point in the eighth round, Edmondson went on to claim a majority decision win against Londoner Azeez.
Their fight took place at the Copper Box Arena after that evening’s main event of Adam Azim against Ohara Davies.
The two had previously sparred many rounds and also boxed in the amateurs, Edmondson also came out on top in that contest.
He is the first British Champion from Southampton since light-heavyweight Steve McCarthy won the belt back in 1990.
“It’s great and good to look back on.” Edmondson smiled as he said.
“I don’t think much will beat the feeling of winning the British title but we know where we’re going and there’s a lot more to come.
“But I’m here to make big scenes at the world level and secure my family for life, we’re getting there and it’s a step in the right direction.”
The 29-year-old is part of a trio of undefeated professional boxers from Southampton signed to Frank Warren’s Queensberry promotions.
Super-featherweights Garner and Royston Barney-Smith also come from the same city.
All three were set to feature on Queensberry’s show in Bournemouth this Saturday before Barney-Smith had to withdraw due to injury and illness.
“We’re three undefeated, good looking lads,” Edmondson laughed.
“It’s massive and boxing has never been thriving like this in Southampton before, I don’t know how many years ago it was that we had a British champion.
“I’m glad to be part of it and I believe that us three are going to make history for this city.”
Edmondson’s opponent Kejawa is undefeated and even though he was born in Nigeria he fights out of Bristol.
In 11 wins he has knocked out five of his opponents, his last win was over the Polish Adam Cieslak at the Brentwood Centre.
“A big knockout is coming.” Edmondson said. “I’m going to take a few rounds, set a few traps and then I’ll take him out.”
