Planning rules set to be relaxed

The government wants to get planning officers "off people's backs" with a relaxation of current rules in England.
The government will consult on allowing people, for a three-year period, to build larger extensions on houses - up to 8m long for detached homes.
Rules on shops and offices expanding and on developments having to include affordable housing will be relaxed as ministers seek to boost the economy.
But Labour says the government is "kidding themselves", as BBC's James Landale reports.
