Stark warnings over G20 summit

Version 0 of 1.

There are stark warnings in several papers about what could be in store for London when it hosts the G20 summit.

The Sunday Express says Londoners will face a massive Â£10m security operation to deal with a terror threat said to be at the "severe end of severe".

And the Observer says staff in the City are being advised to dress down and postpone non-essential meetings.

There are fears they will be forced to run the gauntlet of protesters. "Burn a banker," says one anarchist poster.

High earners

"Cameron faces backlash for supporting supertax" is an Observer headline.

It refers to Tory leader David Cameron's proposals to raise the rate of income tax to 45 pence in the pound for those earning over Â£150,000.

The Independent on Sunday says Boris Johnson is warning it would punish those in the City who would stimulate the economy again after the recession.

In the Mail on Sunday, former Tory cabinet minister Lord Tebbit warns that many voters will desert the party.

Alcohol ban

There are more warnings about Britain's drinking culture in several papers.

The Sunday Express leads with a call for a "prohibition-style" ban on alcohol sales in areas where people's health is being put at risk by drink.

Leading specialist Professor Ian Gilmore tells the paper that advanced liver disease is now commonplace among heavy drinkers in their 20s.

The Observer says the number of women being going to hospital with alcohol poisoning has doubled in five years.

Language and culture

The fate of the postmaster who banned from his post office customers unable to speak English divides opinion.

The Mail on Sunday says Sri Lankan-born Deva Kumarasiri believes anyone who moves to a new country should speak its language and embrace its culture.

The Daily Star Sunday reports "fury as extremists drive out hero Brit".

But the Observer says Mr Kumarasiri has been thrown out of the Liberal Democrat party and criticised by the Racial Equality Council.
