More than a thousand demonstrators are set to descend on the Lib Dems' Glasgow conference this Saturday in a bid to beat back the bedroom tax.

Leader Nick Clegg is expected to regale delegates with a speech describing "a fairer society enabling everybody to get on in life" - in one of Britain's poorest cities.

But campaigners gathering outside the Scottish Exhibition Centre plan to remind delegates of their MPs' collusion in the coalition's widely reviled bedroom tax.
