The week's winners Royal & SunAlliance up 3%Cox up 3%

The week's losersBeazley down 5%SVB down by 0.5%Cox and Royal & SunAlliance (R&SA) were this week's winners in terms of share price rises. They managed the highest increases in the insurance sector with a 3% rise. If only R&SA could sell its struggling life arm it might push its shares up higher.In a statement this week, R&SA finally confirmed it was in 'early' talks to sell the life arm 'with respect to releasing capital'. Last month we mentioned that several companies and financiers such as Old Mutual and Goldman Sachs banker Christopher Flowers were interested. But now other contenders have joined the race. It's understood that investment group Resolution Life and one other have approached R&SA.Analysts have put a price tag of around £600m for R&SA's life arm, but reports claimed that Resolution offered a whopping £900m. But whatever R&SA gets at the end of the day, it can knock £300m off the price, as it borrowed this amount from its life arm to support its general insurance business. AIM newcomer The Broker Network has suffered its first wobble after a glorious start. Last week its share price dropped 20% from 72p per share to 57.5p this week. The company put this down to a 'liquidity issue' and a lack of profile that it said it was working on. A spokesperson said: "It's by no means a reflection on how the company is doing." The jury will be out until its half-year results in July.Meanwhile, fellow AIM newcomer Pavilion Insurance Network had a field day on its first day of trading. Its share price rose from 5p to 6p - small number, but big percentage.
