Yes and no, lloyds is the biggest provider of Current accounts, HBOS has more mortgages and savings.
Because of the diverse investment that lloyds holds it is at far less at risk than most of the uk banks (though this merger has increased the exposure by three times.. :S)
We tried to purchase Abbey in 2001 but were blocked and told to look over seas so this is a big break for lloyds hehe - And lets remeber its a take-over not a merger deal
