A mum wept yesterday as she told a jury how her ex-lover sped off with their children and drove them into an icy river.

Kim Smith, 37, tried in vain to rescue the children when their dad ­Christopher Grady, 42, gave her 10 seconds to "say ta-ra".

He sat sobbing in the dock with head in hands while she gave evidence.

Grady allegedly plunged his car into the River Avon in Evesham, Worcs, last February. Daughter Gabby, five, died days later. Son Ryan, six, survived.

Ms Smith told the jury: "The last thing he shouted at me was 'river'. His face was contorted.

"I jumped at the door handle to try and open it but he went too quick."

Witnesses described how the children banged frantically on the back window as the car was submerged, Birmingham crown court heard.

Grady, of no fixed address, denies murder and attempted murder.

The trial continues.
