The security staff don't police the amount of bags, just the contents of said bags.
I wouldn't worry about the security staff, many airlines allow one bag plus a "personal item" such as handbag/man bag camera case etc... The security staff don't police the amount of bags, just the contents of said bags.
But as a previous poster mentioned the security staff aren't normally bothered about the amount of bags you take through
I'm confused! When did the regulations - as detailed at the top of the first page of the Hand Luggage thread - change? If they have changed and all airports now allow 2 bags then the advice given here needs to be edited.

Each passenger is restricted to carrying only one item of cabin baggage through the airport search point with a maximum size of 56cm x 45cm x 25cm. Other bags, such as handbags, may be carried within the single item of cabin baggage.
UPDATE: Some airlines and/or airports now allow two pieces of hand luggage, while others still only allow one. It is important that passengers check the website of the airline they are travelling with, as well as the websites of the airports they are travelling to and from, as restrictions may differ on the outward and return flights.
But at Edinburgh, for example, you are only allowed to take more that one bag through if the airline you are travelling on allows you to take more than one bag onto the plane but if they only allow one bag then that's all you are allowed to take through security. Every time I've flown from Edinburgh, your boarding passes are checked before you are even allowed to enter the queing area for security and I have seen people at that point advised that they must place all items in a single bag depending on which airline they are flying with. So a lot could still depend on which airports the OP is flying to and from.
