Relay on/off switch Pls help - Electronic Circuits Projects Diagrams Free

Hi,

I need a circuit to switch on a relay as follows,

1. Triger using push button switch to switch on the relay
2. Switch off the relay by activating a LDR (When there is a light on LDR)

Relay should not on while powering the circuit other than the push button trigering.

Pls help me to design this.

Thanks in advance.
