Thousands of people could be without holiday insurance following the enforced liquidation of Whiteley Insurance Consultants by the Financial Services Authority on Thursday.
The regulator is concerned the company has been putting consumers at risk by selling policies that were not underwritten by an authorised insurer.
The firm - which acts as an insurance intermediary - also trades under the names Kingfisher Travel Insurance and Kingfisher Insurance Services.
We asked joint provisional liquidator Dan Schwarzmann, from PricewaterhouseCoopers, who is affected and what they should do.
An emergency helpline has been set up for worried policyholders: 08705 234803
Trading endowment policies
If people have an endowment policy they no longer want, one option is to try to sell it because they might get more money than if they surrender it to their insurer.
A year ago few investors wanted to buy second-hand endowments
Companies which trade in these policies, known as market makers, say current demand is high and sellers can achieve on average 15% more than if they were simply to cash policies in.
We spoke to Jo Bridger from market maker Policy Plus about current demand and asked Mark Meldon of independent financial advisers RC Gray & Co what customers should consider when deciding whether to sell.
Endowment action firms under fire
Prudential has said it will no longer pay endowment compensation to agencies acting on behalf of complainants.
The Prudential has been one of the biggest sellers of endowments
The insurer has spoken of its concern at the size of the commission the agencies are charging, which is typically around 25%.
It said it was worried that some people may not realise they can complain direct and avoid this cost.
In future, compensation will be paid direct to the customer, and paying any agent's commission will be up to them.
We discussed this with Prudential Chief Executive Mark Wood, Paul Coopers of complaint handlers CLAIMS, and Teresa Fritz of Which?

New rules for unit trusts
Investors in unit trusts will be given more information under new rules imposed by the European Union.
The new rules will not be compulsory until the end of September
In future the funds will have to show details of the total charges made each year for running the fund as well as 10 years past performance data and some indication of how much money comes in and goes out of the fund.
The new rules, which also apply to Open Ended Investment Companies (OEICs) will start from 1 May, but they will not be compulsory until the end of September.
The Investment Management Association, which represents fund managers who sell unit trusts and OEICs, largely welcomes the changes. But it does have concerns.
We spoke to IMA Chief Executive Richard Saunders, and also to Justin Modray of BestInvest.
