On tap.

Mr Smith reads that "MSPs will be asked to swap bottled water for more environmentally friendly tap water. Last year, the Scottish Government provided 123,884 litres of water at a cost of £34,201.90 at its offices in Victoria Quay. The Scottish Parliament also has free bottles of water in the debating chamber and committee rooms for MSPs."

That's a lot of plastic bottles ... even if they are being recycled. And rather ironic given the campaign over most of the last Scottish Parliament's last session to impose a levy on plastic bags by MSP Mike Pringle.

Plastic ... it's fantastic.

Mr Smith reads that Liberal Democrat MSP Mike Pringle is to attempt to, yet again, introduce a charge of 10 pence on every plastic bag handed over in Scotland's shops.

Now Mr Smith doesn't necessarily object to the concept or even principle of what Mr Pringle is proposing, but what he does object to is the fact that Mr Pringle tried to do exactly the same thing over most of the last four years of the last Scottish Parliament and got ... er ... absolutely nowhere as regards legislative support.

So Mr Smith asks why he is proposing to waste even more time in the Scottish Parliament on an idea he couldn't get through last time, before the voluntary agreement arrived at last time around has even had a chance of being assessed?
