THE resignation -- delayed a month -- of Sir Norman Fowler from his

post as Tory party chairman, could prompt up to six Junior Ministers to

announce that they do not wish to remain in Government.

Sir Norman, a long-serving Cabinet Minister in the Thatcher

administration, is bowing out to pursue business interests. There are

several Ministers who wish to do the same, but are concerned not to give

the impression that they want to quit a sinking administration.

All of them have spent many years at the Commons and in Government and

can see no advancement. All of them have told the Prime Minister that

their positions are at his disposal when he comes to reshuffle his

Government.

Timing is important to them because they do not wish to be caught up

in the reshuffle expected next month with any hint that they have been

sacked.

Most of them wish to devote themselves to commerce and industry and

important directorships may be at stake.

They would wish the same kind of letter that the Prime Minister wrote

to Sir Norman yesterday: ''You made it clear to me some time ago that

you wanted to stand down as party chairman this summer. I would like to

put on record my thanks for everything you have done since April 1992 --

and for agreeing to stay on in post until I appoint your successor.''

This is widely expected to be Mr David Hunt, Employment Secretary, who

has been wooing the party faithful since last autumn's conference in

Blackpool.

He appears prepared to soldier with the Prime Minister into the next

General Election whenever that might come, possibly to the detriment of

his own political career. If he becomes the party chairman next month he

is likely to have to leave the Cabinet.

Sir Norman quit the Thatcher administration after being in Cabinet

since 1979 on the ground that he wanted to spend more time with his

family. He is chairman of an important industrial group in the Midlands

and now he wants to devote more time to his business interests.

His ''Dear John'' letter to the Prime Minister yesterday said: ''You

have known for some months my intention to stand down as chairman of the

Conservative Party organisation once the elections were completed and to

continue my political career on the back benches. I know that you would

like me to remain in post until you appoint a successor and I am clearly

happy to do that.''

The Prime Minister sent him and his wife Fiona his best wishes.
