Engine cranks but does not start, there is no spark to engine?

I was driving the car all day, no problems at all, the car has always started first time every time. I filled up with fuel, parked it and due to another driver saying my brake lights weren't working I checked all my fuses. I wedged a stick from my seat to the brake pedal to see if the lights were working, they were working. I switched off the car and went inside only to realize after a phone call from the neighbor that I had left my lights on. Silly really, but when you turn off the car the headlights turn off, but the back lights stay on.
I ran back to the car and tried to start it but even though there was still plenty of power in the battery it wouldn't start.
It would just crank and crank but won't start.
Next morning tried to jump start with my other car because I thought maybe the battery was too weak to start it.
Tried starting it again but just cranked over and again didn't start.
I've had a mobile mechanic come to look at it as well. The car was showing No codes whatsoever. The fuel pump is working, and he even sprayed started fluid in the engine while I turned the key but nothing.
He also checked all the relays and fuses as well.
He was baffled to say the least.

Vehicle listed above is a Tk Barina.
