Protesters drop Vince Cable a line

GREEN campaigners are urging supporters to write to Business Secretary Vince Cable in protest at the Royal Bank of Scotland's investment policy.

Friends of the Earth Scotland claims the bailed-out bank is investing in projects such as tar sands extraction in Canada, which they say is destroying the environment.

It is calling on followers to e-mail Mr Cable in protest at the investments of RBS and other taxpayer-funded banks.

The group says those banks are undermining the planned green investment bank.
