asked the Secretary of State for Energy what evidence has been drawn to his attention of the picketing by members of the Transport and General Workers' Union of persons engaged in supplies to North Sea oil rigs at Aberdeen harbour and harbours of other Scottish ports; and if he will make a statement.

I understand that picketing of Scottish shore bases from which North Sea oil rigs are serviced has taken place and I much regret that a picket was killed outside Torry Dock base in Aberdeen. The rigs have adequate essential supplies and normal oil production is being maintained.
