Almost 200 jobs could be at risk after a major insurance firm confirmed it was set to close its Birmingham office.
RSA, formerly known as the Royal and Sun Alliance and which owns the MORE TH>N brand, will shut its existing base in Colmore Row following a review of its organisational structure.
A new commercial trading site is due to open in the city centre in September but it is not yet clear how many people will be employed there.
The insurance group confirmed that around 190 employees were at risk of redundancy, with a consultation period now under way.
A spokesman added that bosses would look to redeploy people wherever possible.
The Birmingham office, in Colmore Gate, currently houses commercial, claims, personal and finance arms of the operation.
An RSA spokesman said: "Following a review into our organisational structure and geographical footprint, we have concluded we could be working much more effectively and efficiently if teams doing the same kind of work, or focused on the same kinds of customers, are situated together.
"This means we will be closing our existing office in Birmingham and replacing it with a new commercial trading site which will continue to serve our local partners.
"We remain absolutely committed to maintaining a presence in the city. We expect to open our new trading site in September.
"Unfortunately, a number of our employees will be impacted by these changes and we will be working closely with them over the next few months and will look to redeploy our people wherever possible."
There were fears over job losses last summer when rival firm Zurich announced that it wanted to takeover RSA in a £5.6 billion deal.
However, the Swiss insurer pulled out of negotiations unexpectedly in September, sending RSA shares tumbling.
RSA currently operates out of 13 cities in the UK, employing more than 7,000 staff.
Birmingham Chamber of Commerce spokesman John Lamb said: "It is always a pity when the city sees firms leave but it sounds like the RSA does want to remain in Birmingham.
"The trend is generally the other way round with more companies wanting to move in.
"We've had HSBC announcing they will be moving in, bringing thousands of jobs, as well as Deutsche Bank in the city.
“We believe that Birmingham is very attractive to businesses, both established and new. We will await the exact details of what the RSA plans to do when it is ready to announce them."
Last year, HSBC announced that it would be moving its UK personal and business bank to Birmingham in the largest inward investment deal in a generation.
The bank is planning to have 2,500 employees in place at its new headquarters at 2 Arena Central by early 2018.
