BOND. James Bond. Tony Blair may find it tough to match the persona of that screen icon. In fact, he may not even match the man who played Bond, Sean Connery. At least not in Scotland, where the actor returns to back SNP's campaign for freedom from Britain. Since the day 37 years ago when Connery turned up for a Dr No interview with 'Scotland Forever' tattooed on his arm, Connery has made no secret of his service to Scotland in opposition to Her Majesty. The SNP announced last week that Connery's been giving the party £50,000 a year.
