Okereke, the group announced a hiatus in 2009 when his solo album The Boxer which was released last year to allow it to function.
Block Party in April to speculate on future Lissack emerged when working on a new album planned to confirm this, while Okereke claimed not to have been informed.
Earlier this month, the star admitted she is not sure if he is still a part of the line-up, saying, "I hope I haven't been fired. I don't really know what's going on, because we haven't really spoken recently and I'm a bit too scared to ask."
Okereke and Lissack again to include the recognition they are tired of waiting and a new singer is looking to hire.
He tells NME, "It's not really a secret because Kele's been pretty busy doing solo stuff and it looks like he's going to be doing that a bit longer. The other three of us wanted to meet up and make music. We were talking about just doing an instrumental thing, but now we might get a singer as well, to properly put some music out and play some shows.
"Because it's the three of us, I guess there'd be some degree of expectation from people to at least play the songs we wrote. I don't think any of us (including Kele) would object to that."
However, Lissack is adamant there is no rift with Okereke, adding, "We've still got the same management and stuff, so he might have known, he might not. He's doing his own thing and we wanted to play together, so it wasn't like we were going behind his back. I haven't spoken to Kele for a couple of months, I guess since the festivals when I was doing stuff with Ash. But there's no bad vibes."
