Members of Parliament travelling back to the UK from overseas to pay tribute to Baroness Thatcher can claim up to £3,750 in travel expenses, it was confirmed today.

The man who provided police protection to Lady Thatcher, Bob Milton, said the biggest risk to the former Prime Minister's funeral is the "lone individual".
