Labour has been drawn into the rail strikes row as front benchers have been told to stay away from picket lines.
Party chief Keir Starmer told shadow cabinet members “we must show leadership” adding “frontbenchers, including [parliamentary private secretaries] should not be on picket lines”.
The full memo, seen by Politics Home, said: "We have robust lines. We do not want to see these strikes to go ahead with the resulting disruption to the public. The government have failed to engage in any negotiations."
