Other Insurance company disputing liability

Hi, this is my first time of posting and would be grateful for any advice.

I had an accident the week before Christmas and I thought it was clear cut that the other driver was at fault but his insurance company today have disputed liability.

I was heading to the shops and turned left at a junction on quite a sharp bend, about 200m from the junction I turned right into the shops car park, as I started to turn the other car had attempted to overtake me and hit me on the side of my car, around the front wheel and driver door

He claimed I was indicating left and not right, which I had been when I turned on to the road, but had changed my indicators before turning. He overtook me on a bend, with a single lane width restriction just in front of me

The damage to his car was around the front left headlight.

My insurance company have requested a statement from me and I have also sent them some photographs of the scene of the accident.

Could anyone tell me if this is likely to be resolved in my favour?

Thank you

Mandy
